You tell Traxxas GTR shock springs apart by color. The rate is marked in colored dots on the end of the spring. This page lists every current GTR spring, softest to stiffest, with the rate, the part number and a link to that exact spring.
⚠ “GTR” is not one spring. The same name covers shocks on very different trucks, and the springs do not swap between them. A Revo spring will not work on a Slash oval car. The rates only mean the same thing inside one table below, and every table says which trucks its springs fit. Check your shock length before you order.
Standard GTR Springs
These fit the Jato, Slash Late Model, Slash Modified, XO-1, Mini Maxx and Mini XRT. It is the set most oval racers are looking for.
| Rate | Color | Part # | Notes |
|---|---|---|---|
| 0.7 | Yellow | #5427 | |
| 0.9 | Orange | #5428 | |
| 1.0 | Tan | #5429 | |
| 1.1 | Green | #5430 | |
| 1.2 | Silver | #5431 | |
| 1.3 | Gold | #5432 | Jato only |
| 1.4 | Pink | #5433 | |
| 1.6 | Blue | #5434 |
GTR Double-Rate Springs
Dual-rate springs for the Revo Nitro, Slash Late Model, Slash Modified and XO-1. They pick up where the standard springs stop and carry on stiffer.
| Rate | Color | Part # | Notes |
|---|---|---|---|
| 1.8 | Double Green | #5940 | |
| 2.0 | Double Black | #5941 | |
| 2.3 | Double Purple | #5942 |
Revo, E-Revo, Slayer & Summit 1/10
The stiffer springs for the big trucks. These fit the Revo Nitro, E-Revo, E-Revo VXL 2.0, Slayer and Summit 1/10, and they do not fit the smaller cars above.
| Rate | Color | Part # | Notes |
|---|---|---|---|
| 2.9 | White | #5436 | also Slayer, Summit 1/10 |
| 3.2 | Orange | #5437 | |
| 3.5 | Green | #5438 | 90 mm rear |
| 4.4 | Black | #5441 | |
| 4.9 | Silver | #5442 | no trucks listed |
| 5.4 | Pink | #5443 | |
| 5.9 | Blue | #5444 | 120 mm rear |
| 6.4 | Purple | #5445 |
Progressive Rate Springs (Long Shock)
For the Long GTR shock (#7461X) on the Hoss, Rustler 4X4 and Slash 4X4. These springs get stiffer the further they squash, so the number here does not mean the same thing as the numbers further up the page.
| Rate | Color | Part # | Notes |
|---|---|---|---|
| 0.623 | Orange | #7440 | softest |
| 0.653 | Green | #7441 | |
| 0.767 | Black | #7444 | |
| 0.810 | Pink | #7445 | |
| 0.892 | Blue | #7448 | stiffest |
Progressive Rate Springs (XX-Long Shock)
The same thing for the longer XX-Long GTR shock (#7462X), again on the Hoss, Rustler 4X4 and Slash 4X4. It is a longer shock, so the numbers run a little higher than the Long set.
| Rate | Color | Part # | Notes |
|---|---|---|---|
| 0.711 | Orange | #7442 | softest |
| 0.762 | Green | #7443 | |
| 0.874 | Black | #7446 | |
| 0.884 | Pink | #7447 | |
| 1.004 | Blue | #7449 | stiffest |
1/16 Scale (Slash 4X4, E-Revo, Summit)
These three trucks all run the same shock. Traxxas sells it as part #7061 and names it "Shocks, GTR composite, 1/16 E-Revo/Slash", and all three parts lists show the same shock, the same shaft, the same caps and retainers and the same rebuild kit. That means every spring below fits every one of these trucks.
What changes from truck to truck is which springs Traxxas puts on the list. The Slash 4X4 gets the four soft ones, the E-Revo the four in the middle, and the Summit those four plus the three stiffest. Read the Notes column as a starting point, not a rule. A heavier build, a bigger battery or a rougher track is a good reason to go up a step.
| Rate | Color | Part # | Notes |
|---|---|---|---|
| 0.82 | Double Orange | #7140 | Slash 4X4 list, softest |
| 0.88 | Double Green | #7141 | Slash 4X4 list |
| 0.94 | Double Tan | #7142 | Slash 4X4 list |
| 1.02 | Double Black | #7143 | Slash 4X4 list, stiffest |
| 1.76 | Orange | #7145 | E-Revo and Summit list, softest |
| 1.92 | Green | #7146 | E-Revo and Summit list |
| 2.06 | Tan | #7147 | E-Revo and Summit list |
| 2.22 | Black | #7148 | E-Revo and Summit list, stiffest |
| 2.77 | Pink | #7244 | Summit list only |
| 2.925 | Blue | #7245 | Summit list only, hard to find |
| 3.2 | Purple | #7246 | Summit list only, stiffest of all |
The colors repeat across the two groups, so orange, green, tan and black each show up twice at very different rates. Check the part number or count the color bands before you fit them: the soft group is marked with a double band.
Other Platforms
The Unlimited Desert Racer, LaTrax and Mini Maxx / Mini XRT each use their own GTR springs, and none of them share rates with anything above. Traxxas does not give a rate for several of these.
| Rate | Color | Part # | Notes |
|---|---|---|---|
| Blue Stripe | #8441 | UDR front | |
| Blue | #8444A | UDR front | |
| Silver | #8444X | UDR front | |
| Blue | #8445A | UDR rear | |
| 0.314 | Red | #7666 | LaTrax 1/18 Teton |
| #10764 | Mini Maxx / Mini XRT | ||
| 1.4 | Pink | #5433A | Jato, XO-1 only |
Shock Bodies, Rebuild Parts & O-Rings
If you are changing springs, the shocks are already apart. These are the complete GTR shocks and the parts that wear out: the rebuild kits hold the o-rings and seals, and the rod ends and boots are what usually goes first.
| Part | Part # |
|---|---|
| Long shocks, Ti-nitride shafts (2) | #7461X |
| XX-Long shocks, Ti-nitride shafts (2) | #7462X |
| Long shocks (Blue) (2) | #7461 |
| XX-Long shocks (Blue) (2) | #7462 |
| Aluminum GTR shock set (4) | #5460A |
| GTR shock body | #5467A |
| Shock rebuild kit (Long / XX-Long) | #7463 |
| Shock rebuild kit | #5462 |
| Shock rebuild kit (2) | #5562 |
| XX-Long shock shaft (2) | #7465T |
| GTR shock shaft (2) | #7063 |
| Shock rod ends (6) | #5469 |
| Shock boots (2) | #5464 |
| Aluminum "Fox" shock caps (4) | #8465 |
| Aluminum "King" shock caps (4) | #8457 |
Aftermarket Replacements
Parts from other brands that say they fit GTR shocks. This list is short on purpose. Plenty of shocks are sold for these trucks, but only these two say they fit the GTR shock itself, and we would rather show two we are sure of than a page of maybes.
| Brand | Part | Part # |
|---|---|---|
| RPM | Shock shaft guards for GTR shocks (4) | #RPM81692 |
| Hot Racing | Aluminum shock upgrade kit for GTR shocks | #HRARVO15608 |
Spring rates, colors and what each spring fits come from Traxxas part data, checked on every product listing on 12 August 2026. The rates are Traxxas’ own numbers, and they only mean something within one group.
