"I like how ya do it! Not the usual exalted rapperwannabe kiddo with hat, here you are a serious man doing a professional review, a calm man that speaks relaxed and put the viewer on a sofa with a warm cover on him." Sincerely, your new sub.

I have mine set up with 10w oil, Traxxas soft springs (I think white rating) and the front drag links adjusted so they don't interfere as much with the axle housing while under full articulation and the bump stop spacers removed. The kit is a bit over priced but it makes a big difference for crawling when properly set up. Made mine long travel.

Ordered mine from my local shop today. $129 for colored kit, $119 for black. As I mention on another of your videos he also sells Sport RTR $299, Bronco $399, Blazer $429. No where online can come close to those prices.

I love the energy of this video. The euphoria and excitement for the hobby is contagious!

I have a High trail and I’ve done very simple mods(adjusting rear shock mounts, softening springs) and it out crawls almost every stock height trx4 I have been around. If you use it to crawl and are are thinking it will have a negative impact, it only takes adjustment for it to work great!

if you want more flex get longer shocks and put them on for a fraction of the price. i did it with my trx-4 tactical

Thank you. You saved me from spending a lot of money pointlessly on rocks, mud... Thanks.

If you install this kit and still want to crawl, I recommend some brass upgrades. Brass portal housings, diff covers, and maybe some steel drive shafts. You want to bring your center of gravity back down as much as you can. Everything else he said is good information.

As for spacer removal, rear is fine front cut in half per side cos if one removes both front the axle will flex more on the passenger side and driver side hits the servo drop mount...

I never thought of the TRX-4 as a Mega Truck but when Harley Designs did that one it looked great. I remember when the TRX-4 first came out Traxxas called it a basher. I don't see it that way.

Nice to see some honest reviews instead of just people trying to sell you the upgrade kits

I just got my kit dropped off by UPS today. I chose the black, not because of price but my choice of color. I personally think it looks better. Not so flashy and eye catching. It is a Long Arm Lift Kit, not a long travel kit. I wanted it to enable use of bigger tires. Not the 2.2 but the 1.9 Super Swamper XL (4.75”)

I think I’ll stick to trying 2.2 with no lift then. I do t want to sacrifice any more high CG on this truck. My dad taught me (43 now :) that he saw lots of high lifted trucks do poor in mud and trails etc because one side would sink or the truck roll. Same with scalers. Dad had a 1977 Chevy Cheyenne 400 small block 35” mudders cut fenders no lift gear driven transfer case. Looking to do the same low stance big tire on his bronco my defender and son’s tactical Tex-4s

I didn't use the servo drop box. I get full compression with mine. You have to add a 3mm spacer between the servo horn and the link. It must be aluminum or steel. The geometry is just fine other than full droop but that doesn't affect it one bit when climbing or articulating over obstacles. With the servo drop box, it would not get full compressing as the Panhard kits the servo horn. Since you're running a droop setup you don't need the servo drop box. Mine crawls like a mountain goat with this kit and over-size 1.9 tires stretched over 2.2 raceline wheels.

I haven’t gotten my TRX-4 kit yet but I got the optional shock towers to remove the fenders so I can run a tucked rock crawler body, I figured could put bigger 2.2 tires without raising the truck. On my real world 4x4 trucks I have always put the biggest tires with minimal lift to keep it lower, 37” with a 2” level kit and fit no problem. A two beer project for a 6 hour project? I would be at 5-6 beers in by then.

Trx-4 (Sport) Love it

Thank you for sharing this with us!!! I was thinking the kit was $190+ tax... I was thinking $80 was going to be pushing it for the cost factor! I suppose $175 painted & $150 black is still a little better than the $190!!! I see everything in the kit and it all looks pretty awesome! But I still have a hard time with the overall cost. So here's an idea for running a 2.2" tire on a 98% stock Bronco. #1 move the front and rear bumpers out one extra hole, so they don't rub on the factory $165 body. #2 pull off, or trim the stock running boards. #3 using a dremel, remove anywhere from 1/8" to 1/4" of lexan from that exotic body. #4 if necessary, add a little longer bottom shock eyelet. I'm pretty sure Traxxas makes something that will work. #5 install a 2.2" 5.90" tall monster set of tires and enjoy. I will let you know how it turns out...

I just installed this on my g500 with yeah racing axles and a pile of brass! What a totally different truck!!! Im using it more for the extra travel than a lift kit. I removed the little stops and used the orange striped springs. I wish i would have gotten the next set down but ill see what happensm

175? Traxxas sure knows how to make a profit!

Thankyou for your honesty. I thought about lifting, until your video. It all makes sense now.

Maui brewing, good beer.

When the lift came out, I wanted it, but then compared tire scale to the scale of the truck and found out it wouldn't work how I want it to. The scale of the 1.9 tires would be like running a 36 or 37" tire. What I did instead is buy some 105-110 Proline shocks. Kept the 105 rod end on and gave it as much droop as I could. I think it works perfectly, or at least perfect for me.

Got one for $158.00 I about shit when I saw that travel didn’t increase. Not for my defender but for my son,’s tactical. He likes mud and it gets too close to the motor. We run pyrax 1.9 so we are on the right track. The bottle didn’t say what oil but I figured it was thick and the springs are def too stiff. I am relieved to watch this and see we can tune it in. Thanks man!

nice to see i'm not the only 1 running fox 20 gold

Where did you go to school Francis? You are one brilliant man. Your narrations are so very helpful all the way to more recent videos.

Have a gen 8 red cat but cant wait to pull the trigger on the trx 4 blazer way cool on the features

Thank you your the only person I’ve heard say the size of the original shocks. Good review 👍

I.just installed the lift on blazer and took about 2 hours and yes it's pretty involved for sure. I just got into R/C and crawling so can't really give my 2 cents on the pros and cons of the lift for crawling. But it sure looks cool. So will fine time as I go and learn. Great vid keep it up 👍

All you need are the link ends from that kit, t-lock cables and 110mm shocks.

Rewatched this after installing the lift kit on my Defender. Gonna grab me some of the softer springs. Although I did remove the shock spacers I went with some 2.2 Proline BFG Baja KR2 for my tires and some dual stage foams.

All they need to do is change the shock towers to be taller and put in longer shocks, leave most everything else alone. This would give us a little more flex without a higher center of gravity resting height. I suppose I can accomplish this on my own, if they just made the longer shocks that'd sure make it easy.

Your reviews are great with great insights about products. I use alot of your ideals they have always worked great. I got into this hobby because of my son he started watching your video before me. Now here I am a R/C ROCK CRAWLER JUNKY. Great job with videos thanks.

You saved me money my friend thank you, very interesting video I've been wondering about the kit for some time, this video just popped on my feed! Love the honesty as usual brother!!

I just added this to my channel as it helped me a ton , Thank you Francis , my Trx 4 is actually pretty sweet now !

Excellent, honest (I wish honest were something we could take for granted, but sadly not) assessment. Good to know since a buddy of mine just bought this kit (to my complete surprise) and he sometimes leans on me for tricky installations. That aside. "15wt oil" caught my ear. There are only two people I know of who run oil that thin. You and me. Ha. Also, I go with the red plungers for faster damping response. FD I don't own a Traxxas truck; I run GTS shocks on my 10ii. Thanks for the video and the channel.

Fantastic review,very very informative,thanks!

I decided to do this, but i have a full interior. And to swap out to stainless screws. Basically i built a new truck, LOL Even without the stainles.

IMHO it would sell more if they drop the price on the lift kit. I still see this kit seating on the shelves of local store for months! Way too expensive C'mon traxxas!

I love the kit was told I'd never get it to work on my redcat gen 8 well it's done and it's awesome

New fan, subscriber here, really appreciate your knowledgeable straightforwardness. Thanks!

I made a mistake I bought my first traxx plus the battery upgrade on the battery total cost was $488 pretty steep now all the upgrades they ain't no joke either I'm going to have to get rid of my truck any takers $300.

Can you do a video of how you fixed the issue of hitting the steering servo, That would be helpful to a lot of people. Thanks Ron

With mine i was able to buy just the links and servo drop box and it came to shy of 90 dollars i believe it was. Then i had 110mm superlifts from rc4wd so i could adjust dampening and their normal size 2.2 mudslingers are about the size of your slightly oversized 1.9 tires. Added some wheel weights and it crawls better than before the liftkit in my case

Alot of your reviews are so informative , if I'm looking for straight Talk on the Good , bad your the main source I reference to, for someone who has been out of the hobby for years till just this year. I have say I like your well rounded none preferential views on the products an even how you tell how a product can help you and its drawbacks... Cheers 🇨🇦 keep up the Great ccontent ... Ps , be great if you could include some more smaller scale content at times like 1/16 I believe ( wpl scale , Mn 90-99Defender / Toyota etc. )models as Most of your content is on 1/10 ... TY.

Thank you. You saved me a lot of money with this information.

I have the clearance issues as well with the servo arm, the key is finding a servo that is close to the specs of the stock servo, which is hard. My promodler and reef servos are still to tall in that particular dimension. I did find a very skinny servo arm made by hudy that helped a lot. I ordered a 3brothers servo to try I think I can make it work based off the dimensions he emailed me. Or at least be a lot better off than now.

Damn son look how heavy it is, with the front tires looking deflated haha love it!

This is such a helpful channel thank you

Put the lift kit in and add wheels weights and it should perform pretty good and some brass on the diffs

Really enjoying your channel Francis...quick question on the long travel kit/servo issue. I tried this mod just for fun and found that my servo almost hits the panhard link at full droop. Did you ever find a way to fix this in your truck? I’m going to keep it this way for a while...don’t want to think about undoing all those steps! Thanks!

I was thinking about getting this but only because im running out of upgrade options on my trx4. I spent tons of money keeping a low center of gravity so I won't spend 175 to reverse my hard work. I do love the red links tho...

another great in depth video. Thank you .

Great upgrades and fantastic review video my friend 👍😀👍

Thanks very informative vid.

Great review thank you for the info everything was on point it didnt take that long to install but still a good chunk of time and agreed any desire in crawling those springs and oil are trash

Le kit long arms n'est pas fait pour le Bashing mais pour le mudding !

Thank you sir, saved me lots of frustration for naught.. ;)

You saved me alot of money

Maui brew co! As if I didn’t like you enough already. Lol. Just bought a trx4 blazer Lipo included kit. Only way I can get a lipo battery shipped to Maui is if it is included in a kit... I have been learning a ton from your videos. Very nervous to get into this hobby with no viable hobby shop on the island. Bought a metal servo horn. Anything else that will break immediately that I should buy?

This is so funny how much you need to disassemble for shocks.

What wheels are those? The red looks sharp!

Im looking to lift my 79 bronco but here in Canada way to expensive for traxxas lift kit ! Was wandering if you could give me the lenght of the upgraded links ! ?

If you're not using it as a lift kit, could you leave the original servo mount in to avoid any fouling snags?

I love your channel! You're honest in your reviews. And your not a sellout to the company's. Thanks

would it be better to just have more droop than get this lift ?

I’m thinking about getting this lift kit for my trx4 kit, just dunno if it’s worth the $130 that’s kind of steep but it does come with new shocks n a bunch of other cool stuff! My hobbyshop must be good cus there price is a lot lower then what u paid for it

Turning a crawler into a monster I’m not so sure about. Upgrade a crawler for better crawling. My 2 cents but awesome video on a great truck

nice review and honest opinions. My trx4 jeep I have designed the perfect combo for 2.2's yet setting near stock height but when needed has more travel in suspention then this $180 kit does..its a sweet set up you should check it out. There is a creek run where you get a good idea of how she stretches.. Im interested in the kit but I wont dump the coin due to I can make it happen already..

Keep up the good work with this channel. Sub'd.

Thank you for your reviews and more importantly, your honesty. I just got the TRX Bronco and want to upgrade to metal axle housings and brass portals. Is there a particular brand you recommend? Treal, or other?

Did you change the motor pinion or leave the stock one with that set up?

I wonder if they addressed the interference problem with the front end since you made this video? I just installed one on a Blazer and there is no interference at all?? Also, what springs did you use? Everyone says to use the 90mm springs on the 120mm shocks but they are way too short. Maybe they stretch them out? What springs did you use?

I know I’m super late, but what weight oil did you use? I installed the lift and I’m trying to replicate your setups - remove spacers - white long travel springs - and the oil

12-13mph is very fast for a crawler. My crawler goes walking speed like 4mph.

Man Traxxas really knows how to rip people off.... that kit should be no more than $99.00 ! I was thinking about buying one, I thought it looked cool lifted with the old school look. But from what you are saying that it is complete junk

I just put a set of 110mm shocks and and dident need any long arms or a lower servo mount or any gear wires

So from watching the channel and looking at all the TRX4 models , here’s what I’m going to try as regards suspension tuning , TRX4 Defender , yellow front springs , white rear springs , 20 weight shock oil for the rear shocks and 10 weight oil for the front shocks TRX4 Sport , yellow front springs , white rear springs , 10 weight front shock oil 20 weight rear shock oil Does this seem correct RC Review ? And would you advise getting yellow springs for the front and white for the rear with the lift kit to achieve more sag ?? Trying to get some feedback before purchasing the lift kit .... in red .... more money 🤦🏻‍♂️ Love the channel , would like to see more on the RC Review TRX 4 sport and what mods you’ve installed 💆🏻‍♂️

I landed a bronco with this kit. Threw in 50w oil to slow things down but im hating how this top heavy rig flops around. Is there a stiffer spring by chance?

If I had two trx4s I would do one with a lift kit and make it more of my mudder rig, I wouldn't do it in it it was my only rig I like the lower look I think it looks more scale.

Ugh, it’s so irritating that Traxass wants so much for their stuff. They could have cut the cost if they made 2 different wheelbase kits and eliminated some of the additional parts you don’t need. I just installed it w/2.2s myself. Black of course lol, offsets and all the brass I could get my hands on plus lower frame weights. With all that and the wheel offsets it absolutely crawls better than stock. I just need to go brushless. The Savox servo is definitely in the way but after dealing with all the clearance issues I’ll be more than happy. Someone in Traxass engineering needs to step it up though. As a lift kit from the Manufacturer themselves, it’s a massive fail. And come on man, Use a decent servo supplier!! Mine crapped out after 10 packs or so OF NORMAL DRIVING!!! So’d my XMaxx Forget warranty, I don’t want the junk electronics replaced with the same new junk either. Waste of time wrenchin’.

Hi sir so I was looking to get into the hobby or rc which would u recommend the redcat gen8 or the trx4 ?

What if you ran just the long shocks on a regular trx4 setup. But with the long shocks set to droop?

How did you resolve the issue with steering servo and front link interferences?

So how would you fix the servo clearance issue? I'm not sure how I should fix it. Tried putting the stick servo mount back in, but the steering arm will not reach, tried a longer arm, but that seems to put alot of pressure on the components, so it might snap something.

I’m typing this early you may cover it but I just did the long arm lift kit on my bronco and put the 2.2” wheels with super swamped on and am having steering clearance issues , the inside of the tire catch’s on the suspension links , any fix’s / or is it something I have to live with

If I need to lift my trx4 slightly, can't I just put 5 or 10 mm longer shocks on it,? I assume unless I go crazy the geometry won't change much.

Thanks for saving me $175 bucks 🤣

Quick question... I have just recently got the proline hyrax 4.75 for my Trx4 defender and they are hitting the body in the front when the suspension is fully pressed. Everything is stock, nothing changed and now when I check with the original wheels and tires even they are hitting the body. I did change the shock oil but that should not cause the tires to hit the body. Please help and let me know where I’m going wrong.

how much weight have you added to the front ? that tire squish!. I'm adding about 300gms in the front. did you add any to the rear?

Santa cruz bikes! nice shirt

I did this not too long ago. I took the shock spacers out ran 15wt oil and put some spacers on the servo mount and flipped a rod so it doesn't touch. What springs do you recommend for the shocks

Do you know if the brushless motors are interchangable with different models?

Where di you get those fender flares for the bronco , im looking for some for the 79 blazer

Is there a long travel kit ? I don't want lift i want wheel travel.

Still trying to find those softer springs, but no luck at all. Could you lead me in the right direction. Thanks a lot. Good video by the way

What springs did you use in this setup?

What springs did you use? It would help if you tell people that instead of saying replace the springs! WFT?

Late to the game but got me a trx-4 sport and what can i say, it is really fun and challenging on a whole other level than to just go out and blast my 3s granite. Love the runtime i get on the stock brushed motor, way over an hour of constant driving with a 5500mah battery. I have been wondering how to get more articulation but as you explained it, it cannot be done without sacrificing center gravity, am i correct? Can you do this kit and add some brass gear to keep the cofg down low, or wont it help?

Do you think using some weights in the wheels and axles would counter balance enough the higher center of gravity (maybe it will be similar to Stock?)
