Make your 1-ton truck ride like a 1/2 Ton! Sulastic Springs! 

THANKS SO MUCH FOR CHOOSING TX TRUCK MASTERS TO DO YOUR INSTALL! WE LOOK FORWARD TO WORKING WITH YOU AGAIN!

relevant content starts after 5:30

I just installed the "Sulastic Shackles" on my 2013 Ford E150 XLT Premium van with Max Tow Package. This van has a 8600 GVW with a front axle rating of 3700 LBS and back axle rating of 5120LBS. This make for a stiff ride when empty. These shackles are great. Really makes a positive difference when not towing our Airstream trailer. Worth the money and I installed them in my driveway with basic hand tools in less than 2 hours. Easy install. Get them!

They are $460 now plus install labor for 3 guys for 2 1/4 man hours. I'm guessing about $250. Sulastic Springs makes them for the rear of mine but nothing for the front. The underside camera during the test ride was great but I noticed a fair amount of lateral twisting. I suspect this will negatively affect cornering performance as this allows the entire rear differential and axle assembly to shift from side to side with movement of the steering wheel causing dangerous sway. There are videos here that show this movement while driving. It is shocking how much they shift from side to side. This is common on trucks and can be corrected with a bar that connects the differential to the frame. So, 5 years later, what do you think?

The fact that the OP hasn't given ANY feedback/review about the product AFTER install...is a pretty revealing opinion of this product. It has "stay away from it" undertones🤔

Added these to my 3500 CC short box Ram, what a difference. Took the sharp impact out of the rough roads. Just finish a long haul with my rv, did not affect the towing while loaded. Good stuff.

Just yesterday I installed these Sulastic Shackles on my 2018 Ford F450 and I couldn't be happier!! Its because of this video that I even found out what these were and the benefit of installing them. It is such a HUGE improvement in ride quality and I cant thank you enough for sharing your experiences and in depth tutorials through all of your video content. If anyone is on the fence or hesitant to do this DO NOT BE! It will be money well spent without a doubt. Thank you!!

I noticed a big difference in the camera. It just doesn't move anywhere near as much as it did before

Your camera stabilized. Huge improvement for filming. I will definitely be installing these.

I bought into these for my 2020 Chevy HD and … wow, what an improvement! In my opinion, these are well worth the money. The original rear suspension “jarring” due to the expected stiff Heavy Duty ride has completely smoothed out. Objectively, it feels like about 70% smoother and even if I’m only close, it’s simply impressive. I’m sold on it and loving my HD even more for all that it can do; now I can enjoy it for its superior capabilities and not be shaken and stirred like before. The front suspension is still as it was, yet this has made the idea of driving my HD, a more excited experience. My bones and body will thank me over the next twenty years (hope), which is my plan. I love my 6.6L HD gasser. PS, I live in frosty Alberta (winter of course), and these shouldn’t have any issue compared to Air Bags that typically due under -20/30 or -40C weather. Regarding the removal of the shackle and interference of the underside of box, the mechanic I hired chose to cut that bolt instead of cutting a groove in my underside and replaced them with new bolts and facing the other way (easier to remove if one had to next time).

Ok..did the install. Took longer due to my shop not having experience. Make sure there is enough washers so it does not hit the frame. I called Sulastic and BTW they was great to deal with, then they called the installer, issue solved and very professional . The ride has greatly improved...great product, very pleased. Thanks Again Jeff

Overloads were the old fashion way to give a good ride to 1/2 to 1 ton pickups, I had a 1/2 that rode as good as the big cars, the heavier ones still rode good as the overloads took effect gradually as loaded. I am not sure when the people ordering pickups forgot how to order working pickups

They seemed to ride better than stock for a bit. I installed these on my 06 dodge 3500 single wheel and just checked 20 mins ago and the rubber bushing is shot and separated on the passenger side already. installed aug of 2019. only lasted 2 years and now I have to figure ut if I want to go through warranty to get new ones as I'm in Canada and sulastics is in the us. just a caution for future buyers.

I just had these put on my 2017 F450. Dealership had some trouble installing them. The upper bolts were hitting the frame and producing an angle to the brackets. Switched bolts to something more like a low profile carriage bolt and it worked perfectly. Glad I did them. Very noticeable difference and I am glad I had it done. I Highly recommend them.

4.5 years later how are the shackles holding up?

Been driving my old 1999 7.3 F250 for the last 18 years...talk about shake, rattle and roll (leafs front and rear)! Shopping for 2017 one-ton diesel (Ram 3500 vs F350). Had not heard that Ram 3500 suspension was so much stiffer than other vendor one-tons. This looks like a great product. In fact, had a Ram dealer recommend this as an after-market accessory when discussing ride-quality and the effect of auto-level rear air suspension option. Many thanks for the quality content you provide!! 👍

I have a lifted Chevy 2500. This sounds like a God Sent. My rear is Very stiff. Thank You So much

Love the silastic shekel but does not require professional installation start to finish from leaving my recliner to getting back in my recliner 38 minutes from gathering tools jacking up the back of truck with a floor jack using hand tools remove the old shackles install new ones 38 minutes start to finish nothing but a 24 mm socket Tip take top nut off with weight on truck eliminated need for 2nd wrench lower on my f350 has a bar to prevent nut from turning I reused factory bolts it came with bolts but the factory worked great

Would love an update on how these have held up over the last few years? Sulastic seems incapable of understanding how to market a product or even build a website. So when I research I find install videos and failure videos but nothing in between.

Would love to see how these hold up with a load in the bed or towing. If these things hold up well, i will probably be buying a set!

Never knew this type of thing existed. My passengers will thank you!

Well, that takes care of one of my concerns about going 5th wheel for travel. Excellent info! H

These were originally velvet ride shackles. I put them on my F350 crew cab These sulastics are the same deal as velvet ride, (sort of like a lord mount) acts kind like tender spring on coil overs. I freaked when the velvet rides came unbonded. Then these came along. They are worth every penny. They will save you money on the overall maintenance. The only issue I had to deal with (and you may very have to as well, is the bolts are put on from the factory from the center out on mine, meaning you can’t pull the upper shackle bolt out. I used a die grinder, replace them with grade 8 SAE same length. Yours might be different.

Id love to hear your five year review! My fear is that the rubber will dry and crack and come apart.

I just bought an f250 diesel to pull a big RV. I was very disappointed with the ride quality. Thanks for posting this video. I will do this Sulastic springs upgrade. I'm also in Corpus. Subscribed!

Noticeable difference just from watching the difference in before and after video bounce. Looks like a worthwhile upgrade for the cost. Nicely done video. Thanks for the continued passion around truck improvements.

Nice upgrade cause F350 DRW is rough!! Thanks for sharing!!!

Seems like there has never been any long term follow up on this product. Also seems like you never installed them on any of your newer trucks. Guess the product doesn't hold up well to long term use.

Wish i would have known about these years ago! Ordering the tomorrow!!! I installed ride rite air bags because people said ‘they helped the ride’ and they certainly didnt. But im glad i have the bags installed i just wished they helped with the ride.

I would love to see the under-fender camera view when you have a full load.

Now that I've seen how they work, I'm definitely sold on this shackles. 2018 F-350 Super Duty single rear wheel , stock height, I will install this torsilastic suspension shackles, with a pair of Firestone air bags ( 5000 series ), and eliminate the extra factory spring of the F-350. Too bad I'm too far away from South Texas to let this guys put the shackles in. You can even see there is less bounce on the camera in the windshield.......Thank's for the video.

Lowering the rear tire pressure of my unloaded F350 from 80 to 65psi, same as the front tires, makes a big difference in ride quality. It's free and doesn't void my warranty.

Perfect timing, Mr. BTBR. I take delivery of my new RAM 3500 Mega Cab SRW with Ram Boxes this week. I will definitely get these and find a good shop in the Huntington Beach, CA area to have them installed. On another note, I want to thank you for your suggestions for finding a 5th wheel hitch for my new Ram Box equipped short bed truck. I just heard back from Reese this morning and they say their Reese Sidewinder will work fine on my truck as the pin box does not rotate within the narrower 49" wide bed with the Ram Boxes. The pivot point is directly under the pin box body, so up and away from the Ram Boxes. My new truck is at the dealer as of today, going out for weighing on Tuesday, so I will probably pick it up on Wednesday. Thanks again for the great videos.

I can tell a big difference in the camera shacking. alot better

I'm surprised you didn't measure the height of the before and after. I gained half an inch when I put'em on my F350 dually. Also I'd like to see if they sag over time from the first install. They do soften up a bit and I can swear I lost a bit of lift but not sure how much. I do recommend them, however. They last a long time and take the jarring harshness out of the ride. I've put'em on my other 4 duallys.

MAN! I've had this idea for my front leafs for years but never made them.... For the rear, factory "normal" rear leafs are designed to act as a ridged , "anti wrap" style in front of the axle to keep wheel hop and axle wrap under control . The rear , behind the axle portion is longer & less compressed. Installing a quality link bar set up to control axle wrap allows you to re arc the front portions and create a WAY softer first couple inches &, rising rate.

I am looking for used 1-ton truck but I really don't know about truck. So I watched your videos but still I don't know which one is good for me. Your video helps me to get to know about Trucks. Thank you for all good information. Have a great day!

it seemed to carry over to the camera well to display an improvement, pretty cool

Nice, they work compression & in tension. Also allowing the spring to lengthen & shorten freely....

Never heard of something so simple! Thx for the info, might get a set for my 17 F350 Dually.

I read some, not all of the comments but has anyone mentioned the use of an ultraride chassis air suspension by Link manufacturing? That is a huge improvement over the leaf springs also.

It appears they make fronts as well. These guys installed them on a Superduty. Id think you'd be even better off with a set on the front as well.

In 2014 I ordered a new 2014 Ram 3500 HD Crew Cab Dully Longhorn, and I also put these Sulastic on my truck and it changed the ride in the truck so much for the good I could not begin to believe my luck. This is the best thing I've ever done for $500.00 with my clothes on. LOL. I've had Dulles since 1978 of all the different makes. This was my first Ram and I ordered it without test driving one. Well, when it came in to the dealership I was so excited to see it and sign the paperwork and get on the road home I didn't get to drive it before paying. On the way home, I almost lost all my fillings in my teeth from the ride being so harsh. I was not a happy camper. Not one single review on the new Ram one ton 3500 HD talked about the hardship or the ride. It was way worse than any other truck thatvI have ever owned. I was very concerned. I started to look around and talk to other shops looking for help. I also had to lower the rear and front of the truck. I was getting a nose bleed and had to carry a bottle of oxygen because I was so high up. LOL. I tow a 40’ race car trailer set up for formula cars and it sits a bit lower than most other trailers. At the time I had the rear suspension lowered by way of reversing the rear springs. I had not received the Sulastic and drove it for another week with it now dropped 4” (perfect) but without any better ride quality (wishful thinking). When the Sulastics came, I was never so glad to get a package in my life. When I picked up the Ram and drove home after the installation, all my prayers were answered. The difference was day and night. I can't begin to tell you or anyone how much better the ride got. I love this truck. I was delighted to see your RU-vid video with the installation, and you conclusion was the same as mine. I have a question; every company out there is in the business of lifting the trucks and no one is dropping a one ton just 2”. I believe just getting new springs made 2” shorter (correct thickness of wire) and change the bump rubbers should do it? Ted, Newport Beach, Ca.

I put a set of Velvet Ride spring shackles on my 1993 F250 back in the day. Same concept. They worked great. But, the company stopped making them. Great to see that they're available again!

So, 4 years later... how do they hold up?

Watching your videos pre install thru the camera action there appears to be a tremendous difference. Thanks for the review as we are planning an upgrade in trucks.

The sulastic spring does not make a huge difference. It will soften the ride a little but all it does is take the harshness out of bumps. I would not say its price reflects its performance. I have had them on my truck for about a month now.

They still holding up?

What's the average life expectancy of a set of these under normal use? And once you get to the end of the life expectancy do you completely replace the unit? Will there be symptoms that they need replacement? The reason I ask is we pull a 42 ft 5th wheel and would hate to have one reach end of life or break and drop the entire spring assembly....Answers would be greatly appreciated. Thanks

That F350 at 9:58 is gorgeous!

Does it affect the truck or rear bed-load-capacity? Noticeable improvement. Even when comparing immediately after the installation , truck did get much quieter.

Yep! I opted for an f350 DRW to pull my 5thwheel after getting good information on tow ratings from your channel. But I'm pretty excited about the shackles you reviewed as a stretch of highway near me wants to fool me into believing my drive shaft is imnalanced!

Any review updates? Still working? Any smoother with age?

Wow, this is exactly what I need on my 1990 Chevy 1-Ton 4x4 Dually. When it is unloaded and I hit a pothole or speed bump it feels like someone hitting the base of my spine with a sledge hammer.

Do you still like the Sulastic product, or have you moved on to something better? Have the failed over time?

I had pinched nevers in my back and 1 ton is not making may back feel better.I think this is great idea. If you could even do more thing like to you suspension would be great like added air bags or air shocks.

I bought these just after this video, put about 15,000 miles on them, and they failed. I tow an 11,000 lb trailer a couple times a year, but I rely on air bags when towing. The sulastic was for around town. Sorry, after a couple years and 15,000-ish miles, these should not fail.

After watching this video I'll be getting these for my future pickup. Wish these were a factory option on all HD pickups. I feel they would sell more because ride would be smoother overall.

Can you do a review of a Nissan Titan (ideally the SL trim or higher)? I drove one last week from Phoenix to San Diego and back and wow, what a wonderful ride. My girlfriend was with me and she and I were so comfortable. The passenger seat reclines almost 180º and the engine has some serious power and sounds glorious. I think it was the smoothest ride I've had in a 1/2 ton pickup. Only drawbacks are the light (kinda cheap) feeling of the doors and hood as well as the awkward wood trip on the interior. Would love to hear your thoughts on it!

Our local john deere dealer come up with similar item that is front spindles for the z trac mowers and as with your video shows, their's made a huge difference on the zero turn mower's.

Installed them on my 06 Chevy 3500 dually about 8 years ago. Noticed quite an improvement though the truck does remind me that it is indeed a truck on RR crossings & major pavement joints.

The less vibration in your camera alone is very obvious. Assuming it was mounted the exact same way as before. Which I have to assume you did. I just bought a duramax a few months ago and have been asking around, how can I soften the rear suspension and the only answers I get are "it's a 3/4 ton truck, that's just the way they are". That's just an unacceptable answer and I know there has to be a solution. Getting a set of these installed very soon now. Thank you for the video.

After watching your video I was impressed and immediately called the manufacturer with some technical questions since my 2017 Ram DRW has the factory auto air leveling system. I was really taken back by how ill-informed, rushed and rude the representative was. I got no answers. IMO this product could be useful however I actually use my trucks and often tow total gross vehicle weights at over 35K or haul a slide in camper weighing 2 ton plus so having heavy weight on the rear plus the need to know how this product would affect the automatic factory leveling system and the products max load handling capability is a must. I need definite answers and guarantees before experimenting on a product that in failing could leave you stranded and possibly damage the truck, when the manufacture can't or will not provide it I am staying clear. (probably a good product for the guy who hauls small loads once in a blue moon.)

Does this hurt the side to side stability at all with extra amount of free movement and extra rubber?

With my 2016 RAM 3500 4X4 dually and factory air ride, I first opted to install the Rancho rs9000XL adjustable shocks; since sway of my truck camper is my biggest issue Unloaded, these shocks softened the ride quite nicely when adjusted to the softest settings. Loaded with my 4000lb slide-in camper and shocks set to stiffest setting, also improved the ride by reducing the sway and bounce. Next on my list is the Torklift Stableloads, then I will make a decision to go with Sulastic or not. BTW, with the factory air ride, not OEM or aftermarket sway bar is available yet for 2016.

Thanks for the video, I have a 2001 F350 4wd SRW Crew Cab Lariat. The carpool guys hated the ride so much they told me either bring another vehicle or you're out of carpool. I did end up using my Grand Caravan for the carpool and the guys loved it. Despite that I do want a smoother ride, so I think it could make the difference in keeping the truck. Thanks again for the video. To bad the promotion isn't going on anymore I could have used it in a few weeks when I'll probably be order the kit, both front and back. Best Wishes & Blessings.

ordered..looking forward to putting the Solastic in the rear and the Wicked Extreme Duty Heim Joinst steering Drag link in the front for improved steering and control..then off for a front end align.. Thanks for the help.

Oh wow when he said that street name Alameda I knew it was Corpus Christi Texas

Can you do an update on the Sulastic shackles. I just installed them on my 2008 F450 dually 4x4. How do they work after they are broke in with several thousand miles..

I installed them on my 2004 F250. What I notice most is that the sharp hits are no longer present. They do help but not as much as I had hoped they would. Maybe in time they will get better.

Great review! I'm across the bridge, in Portland, and will be getting these as soon as I'm able on my Ram 3500.

I have a 2002 F250 SD, we just got home from a 3500 mile trip to North Dakota and some of the roads were so rough that my wife’s bra broke so I am ordering a set today

Ok this is a new one on me too , I have been lifting trucks and so forth for 40 years and have never seen this but it makes since I am impressed with design I guess as soon as I get a few extra bucks I will order a set for a 1 ton truck I have if it works as well as I anticipate then I know many truck owner friends I will end up having to do at least another 50 sets , at least its ma easy install

If you use a smartphone there are a number of free apps that measure vibration. You could use one of these to put hard numbers on the improvement.

God!! I have spent so much money on trying to improve my ride. I have an 05 Silverado 2500HD with CST 9-11" (set @9") Fox Shocks with reservoir (revalved to softest); and it still rides very rough. I can feel all the bumps and cracks in the street. I have been online and RU-vid everyday trying to find ways to smoothen my ride or find a video like yours. Luckily I came across your video and I'm sold. I live in SocCal, so now I have to find a should that would do the still install or even carry the Sulastic Springs.

Great video! How well did these hold up? Did you carry heavy loads with them? I max out my F350 with a truck camper and am wondering if the Sulastic Springs can handle the load. Thanks, Kevin

Reminds me of a Dexter torflex axle. They can run 10,000 lbs per axle with no issues.

F250 took me 5 hours. 4 hours on the first side because I kept adding (and changing location) spacers. I had to run to an auto parts store to get a 9mm hex socket. I'm not a mechanic however am mechanically inclined. Was supposed to torque to 165ftlbs but my torque wrench only goes to 150. Even that was a challenge for a 145lb person. Let me know how much an install should cost on average. Thank you.

I saw others asked but I don't see an answer. Are they still holding up? Seeing other posts saying they fall apart over time. It makes sense as the design seems to be borrowed from motor mounts but working a lot harder and under more frequent movement.

That looks like one of the better roads in michigan lol

I bought these for my 08 f450, I would not recommend them as the rubber breaks down quickly. I had to go back to stock after 8 months since the rubber was ripping apart.

Hey, will these fit and help the rough ride of a 2018 ram 4500 4x4?

Installed Sulastic shackles on my 2016 Ram 3500 2WD with OEM rear air suspension. Easy install, took 1 hour 20 minutes. I drove the hour home from the office/shop on varying road surfaces and speeds and did notice a very light reduction in the impact from minor jolts such as pavement joints and small ripples. Keep in mind I have the OEM air so it already road pretty smooth. Was it worth the +400? Time will tell. The next mod is a pair of Thuren front coil springs.

My question is what affect does the sulastic have on on the towing side. Does the extra weight destroy the bushing? When towing on a normal situation the ride gets nice and comfortable,what happens to the bushing when towing?

There used to be a similar product like this called velvet ride shackles.my father and I both installed them when trucks were new and 400k miles later still no issues. I don't know how these compare.

Kinda curious about the life of these and what is a failure like?

Everyone asking, how are these are holding up?

you don't hear quite as much rattling in the truck as much for sure. good info here good video man. making me think

It amazes me of those who buy a new pickup, immediately jack it up in the air with heavy duty springs, shocks, airbags, bigger tires and all the other bells and whistles so they can win a pissing contest about who has a "tougher" truck. Then....they bitch and moan about how it doesn't ride like a luxury car. Sell your truck, buy a Rolls-Royce Ghost and load your side by side, bass boat, fifth wheel, horse trailer, tractor and all the other baubles on the back of that cushy Rolls and drive off into whiny butt heaven. Gimme a break!

Would be nice if they had these for a 12,000# rated steer axle on a semi-truck and maybe something for the rear airride to smooth them out. If they just had these alone on the steer axle springs, it would make them ride much softer which would make a world of difference.

After 2 years, how are they still performing? Did you add anything to the back end to make it even smoother? What can or have you done to get the front end to be smother?

No more camera shake that goes out of focus. Amazing improvement

Can you give us an update if you noticed the damper removed?

Looks like a nice product... wish I had them when I had my 94 f250 heavy duty... hard ride when mt

SA 07 Failed in 3 weeks! Great ride for a couple weeks though. The shackles relaxed and we'e resting on their own bump stops in 3 weeks. Worthless at that point. Worth $400.00 for less than a month......I don' think so. I' currently going the warranty route. I wI'll try the HD version upon exchange but not too optimistic at this pount.

Another great video, I really enjoying your channel! Keep up the great work!

How much was this installed?

Thanks for doing this, I thought I wanted these, now I'm sure

Is this still your go to for getting ride improvement on a Super Duty. I notice you made this video a few years ago. I need to soften the ride on a SR F350. Please let me know what you think.

I will be Installing a set on my 2017 3500 ram mega cab duallyTomorrow I’ll keep you posted. How I like them and the improvement of the ride.
