Rebuilding Ultra Shocks | Traxxas Support 

Thank the lord that this channel exists

At 3:40 you show inserting the shaft back into the shock body. I found that if you don't tighten up the bottom cap that has the two O-rings and spacer, it is a LOT easier to get that shaft through the bottom cap. Tightening that bottom cap before inserting the shaft causes expansion of the two O-rings making it harder for the shaft to insert through the bottom cap assembly. In fact, I would think that sliding that shaft through the O-rings after the cap has been fully tightened can cause abrasion and damage of the O-rings from the threaded portion of the shaft. Thought others would like to be aware of this tip.

Who else loves the Traxxas support background music XD

I probably wouldn't grab the shock shaft with a pair of side cutters. It'll put a nick in shaft. Just use a set of shock shaft pliers.

Oh yeah Traxxas is hitting home runs !!!!!!

funny enough i actually was disassembling my shocks earlier today, and i couldn't figure out how to unscrew the top and bottom part. i figured i would use my screwdriver to put into the hole, and (the thing used here) for the bottom part. and that was without watching this video first!

I'm a simple man, I see RC stuff and I click.

My plastic spacer in between seals on my Traxxas TRX-4 shocks were far too big. This caused the seals to be pinched when replacing the lower cap. I sanded mine down but hopefully Traxxas takes note of this

Great vib, you save my life 🤝

Question guys. If the shocks are to be filled up fully. Then how is it that if the shock is too full and won't depress/ Release some oil for the fix. That part made no sense bro. Can you clarify/ is there a shock style or brand that needs this method of taking some oil out to make it depress. Or are shocks easily overfilled and becomes stiff. I'm new to the hobby just learning. Spent 1300on a mini revo and a crap ton of gear and upgrade parts. 4 extra batteries and all that good Jaz. Anyways why I ask this is because I have 80 weight oil and will do my oil change after I watch some shock maintenance Videos. Nice video Brutha 👊😎

This was a lot of help. Thanks!

Amazing video!!! Love your guys cars!!!!!😄

Thanks traxxas! Really helpful :)

Ty soo much

Thanks man that just happen to my rustler vxl cool shot off I fixed thanks to u but need new shock tho

Please can you guys make another nitro support video for after run maintenance and maybe cleaning?

4:51, nu shock are not coming back up, how can i fix this?

Good video! Thanks.

Love it

On the website it doesn’t specify to pull the shock shaft out before the top cap but the vid helped thanks

So I thought that rebound was not ideal?

What does it mean when the shock doesn't bounce back ????????

Just bought a new rc and I love the shocks. How do I get my older rc like the new one?

The amount of bent shafts Ive had is absolutely ridiculous. WHY DONT THEY MAKE THEM THICKER?!

I need some help, my ultra shocks have oil on the shafts after they compress. The seals are absolutely perfect so no oil ‘should’ be leaking. Should I just buy big bores and forget about these?

For me this does not work, I use the original shock absorbers from the Trx4 Sport and if I fill them exactly like that, they can not be pressed together ...

Pls more video on slash VXL brushless 2wd cause I'm getting it

Hello TRAXXAS I know it’s a long time since you’ve made this video I do hope you’ll see this My question. Is how comes with the TRAXXAS x maxx shocks their built with no rebound like I think pro racers would use the term a dead shock yet these slash shocks are built with rebound🤔 Thank you for making this video

Lol I ran the left tire of my bandit vxl into a mailbox...

Is one bottle of 30 ml of shock oil enough?

Nice

can you do this for the gtr shocks plz? i have a hard time getting the right amount oil in the shocks

The ultra shocks are ok but i like the Big Bores or GTR’s.

It's been 2 hours of trying to snap in the top e clip to the shaft. This step seems nearly impossible and I doubt I'll be able to do it anytime soon.... Absolutely frustrating.

I just recently purchased a Traxxas UDR and I am having front end problems ...when I turn and accelerate the front end shakes. Can this be a binding issue in the front differential?

What about a squeaking shock?

The shocks on the slash 4x4 are bad. Today i went to a skate park i didnt go to crazy with it and 2 shocks got the top cap ripped off. Also the plastic driveshaft on the rear keeps breaking. My dads senton got a hell of a beating and it survived only a tire blew.

What shock oil comes in the stock ultra shocks, I like the way my Brushless E-Maxx came and it still has the stock ultra shocks but I broke 2 and ordered more but don't know what shock oil Traxxas uses. I've got a bottle Traxxas silicone shock oil and not sure if that's what came in my truck

What could cause one new shock to move back slower than its paired shock?

i put new oil in my slash shocks, rear ones are fine but the fronts are just like pogo sticks

my shock aren't rebounding unless there is a spring in place, Is this a problem?

No locktight?

do i need to lubricate the shocks? and if yes what lubricant use?

Never use side cuter

Are spring retainers all the same size for different cars

My ESC XL5 on my slash 2wd doesn't tern on and my battery is fully charged I don't know what to do can someone tell me what to do please and thankyou.

Good morning Traxxas.

I'm trying to rebuild emax 3906 and everything is Rusty

I can’t get the shock cap out I’ve tried everything

is this for traxxas slash 2wd and 4wd?

Is this cheaper than a new shock?

Traxxas Ultra Fragile shock shafts. Why name them after any other very fitting word.

My shock shaft is bent at a 90 degree angle

Oh my I thought I had to buy new shocks mine are used asf and I could not drive my rc

Can I use 5W40 or 5W30 engine motor oil to fill my shocks?

How much oil do you put in initially prior to final filling?

Can't seem to get the shock out of the a arm

My ultra socks, kind of bent

I wish I could get RC car but we are poor

Rebuilding ultra shocks is a nightmare they never work properly

It’s going to leak out the oil now lol

I just but motor oil to my rustler's front suspension

I feel like it would be easier and cheaper to just buy a hole new set of shocks for $20.

No hate but ultra shocks ARE CRAP! The caps always pop off and the shafts bend easy ( if your a basher)

1st

i like how that shock was FULL of oil. FACT its not that way from the factory. Fact its almost empty from factory. Go ahead ask me how i know. I litteraly just did this on a slash less than 3 weeks old..... BS btw. it should be FULL NOT HALF EMPTY. Traxxas you owe me 17 bucks for shock oil.
