Default How To : GTR Shocks on 2wd Traxxas Slash

I posted this in my thread with some different text and with out the how to part, I figured I would start another thread for this topic as during my research I had to go to several sources to get the best solution.

You will need...

4 Traxxas GTR shocks

4 Traxxas Jato "orange" 5.1lb. rate springs
(not shown, waiting for the postman, will update photos when they arrive)

2 Traxxas ultra plastic spacers from the lower section of a ultra shock body
(black plastic spacer between the two lower seals - part # 2362)

all the ball mounts from the factory ultra shocks

2 Traxxas front upper camber rod link ends (part # 5525)

2 screws that are longer than the existing upper rear shock tower screws by approx 1/4" or 4-5 mm

1 tube of 5min epoxy with a few toothpicks (for mixing)



Let's Start...

1. Remove factory shocks from your truck, making sure to keep all hardware.

2. Remove springs & spring cups from all of the the revo shocks.

3. Replace the front stock revo springs with the jato springs.

4. Replace the upper & lower ball mounts on one pair of revo shocks with the upper & lower ball mounts from the factory xl ultra shocks.

5. Mount the pair of shocks from the last step (4) in the same manner as the original front shocks on your truck.

6. Remove the linkage ends from the remaining pair of revo shocks.

7. get everything lined up and in order before mixing epoxy.

8. mix epoxy with toothpick, fill long rod end until approximately 3/4 full

9. Now slowly work the threaded shock end in and out of the rod end to ensure there are no air pockets, at this time also use a paper towel to wipe any excess which has oozed out.

10. Set shocks on their side to cure, I made my rod ends have a slight angle as to clear the rear upper camber links better, that is up to you if you would like them perfectly straight or with more clearance.

11. Once epoxy has cured, switch the remaining ball mounts from the xxl ultra shocks to the revo shocks, also replace the revo springs with the remaining jato springs.

12. Using you longer screws place them through the upper mounting hole of the revo shocks, followed by the small back spacers, then tghten to shock tower.

13. Use factory screws to secure the lower shock mount to the rear a-arms.

I had a question about if the upward travel is limited by the shorter shock stroke. Here's some photos, the truck will bottom out in both the rear and front before it coil binds.

Currently running Jato Orange (5.1) & Green (6.3) springs with great results...

so when you put the apoxy in the rod end dos it harden or is it not able to be removed once put together.

Is there a difference between using these and the Jato shocks? I just fixed my buddy's Jato for him and I noticed the shocks with the threaded bodies. Anyone ever came up with a solution that doesn't require the epoxy? What about making an upper mount to lower the upper end of the shock instead of making the shock longer?

I modified these using different approach...

It is possible once the epoxy is set using care to unthread the shaft from the end rod (depending on the type of epoxy you are using)

Maybe use JB Weld. I know you can drill and tap JB Weld once it sets.

Or modify the shocks like I did for my LCG slash truck and use different shock shafts, if your concern is being able to completely disassemble the shocks for service.

Why go to all the trouble??? Get some Big-Bores ,valve and weight right. No brainer. Sure you don't have the cool threads, but so??? The Pre-Load spacers work just fine. I admire the fab-quest, but sometimes, after 30-plus years of doing this stuff, I've finally came to relize those dudes drawing this stuff have somewhat of a clue, maybe not perfect, but they have a clue.

I will agree that big bores are the most popular/ best bang for buck shock replacement for a slash if some one is looking for a bolt & go option and has no interest in killing an hour or more rebuilding shocks.


There are 2 types of hobby enthusiast,

1. one that buys the best, check book in hand & bolts it on and is happy.

2. one that tinkers with everything and treats it as a "hobby" to pass time and relax regardless of the results or that they could buy something bolt on ready.

I think of myself as the 2nd type...

I agree. I got back into the hobby when crawlers started getting popular. Sold my T-Maxx that hadn't ran in a couple years and bought a TLT just after they were discontinued. Built my own frame with metal from the hardware store and learned to braze. I don't think Axial was even around yet. All my crawlers have been kits and even when I got my used Slash I tore it completely down and built it back up, more to see what it needed than just to do it. I love the scale trucks as I like building them and making things more than anything. Guy sent me an extra chassis when I bought my slash so I'm thinking a scale solid rear axle trophy truck will be in the works before too long.

maybe they do have a clue...but i dont like the lenght of the stock setup...the shocks only have to be 90mmand the gtr shocks have a nut that holds the piston in not an e-clip...those e-clips wear out way too fast.

A less hokey method of extending the lower rod ends is to use HPI Savage shock ends. They are longer than normal, but still a 3mm thread.

HPI part# HPI85050

IIRC the plain traxxas balls will fit them.

Granted, I only run my GTR shocks on a heavily abused, but slow SCX scaler. While I run a couple sets of plastic Traxxas shocks, and a set of the aluminum big bores, in my go-fast basher rigs.

Based on my experiences, the GTR is a far superior shock. It has a larger diameter piston, and has a better piston retention method. I always hated how the E-clips would sometimes let the piston float a little on the shaft.

The GTR shafts are harder to scratch, and the lower seal holds up much better. They also come with factory bumpstops that hold up better than the nitro fuel tubing I had been running.

Here's how I mounted mine up. If it works good I'll make the bracket out of something stronger than styrene. Got my Jato springs on the way.
