Traxxas UDR Suspension mods 

Awesome video excellent truck WICKED slow motion shots so cool what a major change

Finally, someone has taken my idea and built it. Nice job!

Nice mod man!! Excellent job! 😊

Nice mate :)

This was a good idea as it eliminates the back squat the car usually has. Great viseo

Love it. It look like its working well.I might do that too. Thanks for the video. Love your channel. 👍🤘❤🇨🇦

Looks great going to try it out .just a tip if you take the two spare tires off . and put two other tire and rims of a lesser weight your udr will almost stop popping wheelies. i found some old rims and dirt tires and it looks great and performs better . helps keep the front end down . also going to switch out rear differential. and put front in do not like the locker always flips right . just some hints . have fun your RC buddy Bill

I just bought a udr wow did you ever change how it drives. What a difference..looking forward to more udr vids.thumbs way up.

That’s a hell of a roost with those paddle tires.

Damn, 👍🏿 powerful 💪🏿

The droop is caused by the weight of the two rear tires .do not forget that trophy trucks have the weight of the engine, and your shocks will brake those stock trailing arms .thanks for sharing your video with us .

I like those shocks on that...like you said especially on a track...

Update on this vs the Super Baja Rey pls! 🤙🏻

Needs the full suspension travel I think. But it definitely landed better. In my opinion it would be perfect if it can get tuned to where it doesn't bottom out from some normal jumping. Stock it bottoms out to easy with normal jumping.

Love it.. running on 8s

Nice work. maybe mount the shorter, double spring shocks you used further inboard on the trailing arms? should get a touch more droop back.

👍👍👊👊📹📹 nice I just got my paddle tires for my udr also!

Damn i need to get a second udr then.. One to hit the track with limited droop and stifer swaybar. And one made for bashing with the full on suspension travel...

What motor and esc? It was flying!

Great vid, only one way to find what works best for you is to try it out! Can you change the bar in the sway bar, maybe you can make a stiffer one!

I just purchased a udr been watching your videos really good to see you test your parts any idea the weight of your udr with all that aluminum thanks Dan Mo.64093

What was the final results?

Great concept but you are right in thinking that you should have still left all the stock suspension travel. That's a huge reason why trophy trucks run like they do over rough terrain. You NEED that high amount of droop to allow for the wheels to drop down into holes and ruts and maintain contact with the ground. The issue as you have noticed with this and pretty much all RC trucks is the lack of bottoming out resistance. I love your idea of adding a secondary spring to start changing the spring rate towards the end of travel. There are many ways to go about having that same end effect but the basic concept is to make the shocks progressively stiffer as they get very deep into their travel. Loved the video and the tinkering! That's what it's all about!

What were the shock's name again?

What wheels and tyres are you using (the sand set up?) Cool vids

Looks a little to stiff for track use but at the same time making shorter limit straps for rear would’ve had same effect and adding more preload to springs. Just giving some tips to help keep it from bucking in air as almost all solid axle rcs do it. Great idea though hope it works for the track

definitely handles better for racing, but loses some of that scale look/feel for me. to each their own. Curious what motor esc you're running, or is that just what a UDR does when it has a tire that can grip on it? I run mine on 6s all the time but its never ripped like yours does!

What kind of engine and esc are you running, and batteries?

You put the spacers where?

What were the shocks name again?

Great idea, the stock suspension is amazing to watch working and all but it just rolls over too easily to me. I’m gonna set mine up for a track. I still have the Only one in Mississippi so far (as of a few days ago anyway) and I’ve broken a rear trailing arm, which became available the day after i broke it so it’s up and running again! I Snapped a front lower a-arm pin- made another one with 1/8” stainless tig wire. Just been having a good time with it too. The front diff was leaking Bad, talked to Traxxas and they sent me the rebuild kit, grease, and oil. It took Seven hours to install and get running again but what an experience it was! Right now I’m installing carbon fiber vinyl on the panels on the sides and it looks pretty Sharp without the body. Have new numbers on the way and my last name will replace Lofton. Sorry for the long comment brother but i had to share! Keep your UDR Vids coming...

It's always a trade off between mechanical grip and car behavior. Loose=tire compliance Stiff=responsiveness

Went from amazing trave udrl to bouncy ball udr

Should change the rear swaybar instead of shortening the shock travel. Stiffen up rear helps eliminate bodyroll but also suffers bump absorb.

Nice video! I would put the old shocks back on. The shocks you installed are too short for the UDR, so the suspension is being limited by the travel of the shocks. Every time you go over bumps and whoops, your truck looks like its bouncing rather then your suspension taking the impact. Also, the additional springs you added is making the UDR suspension stiff.

Not sure if your still answering questions on here , but how do the paddle tires run on concrete/pavement? My original tired in the back wore down 😇 & I was thinking about getting paddle since they have more meat on them

J is that 8S? awesome vid

Bad ass. Suspension looks like it’s doing a good job with the mods

it’s like lifting a touring car.. 🤣🤣🤣

Good Video I would have left all the travel in the suspension. It's a desert racer , not a track car💪👍👍😎

What are part numbers for those internal springs?

Does it matter to have 2X sets of paddle tires on it?

whats the name of those paddle tires?

How do you like the tires?

bro is it hard to change the lower front A Arm? i just mangaled one lol

What’s the length of the shocks? Will they work on a slash?

How hot is it there I live in AZ so if I get one I want to know how heavy ill have to go on the weight.

What wheels are,you running

What pinion and spur youre using sir?

Idk it seemed more stable & had less body roll

Wow that thing shifts. Are you running 6S?

the car seems to go faster

Use thicker fluid on the stock shocks and it will be perfect why kill suspension travel because it sure sounds like you are still useing stock 30wt shock oil

Looks like it hobbles around now=[ took all the suppleness and forgiving out=[ that's what makes a desert racer a desert racer!!=(

that thing is way to stiff... it didnt take 5 seconds to see it!!

this car iou want a track cars not ment for a track if you want a track car you should go get one

I think it handles like crap now.

Now stiff like a boring SCT.....

What were the shock's name again?
