Traxxas GTR vs Pro-Line PowerStroke Quick Verdict
| Decision factor | Traxxas GTR | Pro-Line PowerStroke |
|---|---|---|
| Best for | Most Slash owners who want the simpler Traxxas parts path. | Drivers who want more suspension tuning range. |
| Avoid if | You expect a complete spring-included kit without checking the listing. | You want the easiest parts-matching path. |
| Main Slash part path | Long GTR shocks such as 7461/7461G/7461X plus XX-long GTR shocks such as 7462/7462X. | PRO606300 front shocks and PRO606301 rear shocks. |
| Spring situation | Traxxas GTR shock pairs are commonly sold without springs, so verify spring part numbers separately. | Dual-stage spring setup; optional Pro-Line spring assortments are available for tuning. |
| Oil situation | Traxxas GTR product pages list included 30-weight silicone shock oil. | Horizon/Pro-Line says PowerStroke shocks are pre-assembled and need oil. |
| Main buying risk | Ordering the wrong length or forgetting springs. | Buying front shocks, rear shocks, spring assortments, or rebuild kits by mistake. |
How This Slash Shock Comparison Was Made
This comparison is based on part-number clarity, Slash fitment, spring and oil requirements, tuning range, rebuild path, and the mistakes most likely to send a Slash owner to the wrong listing. Product examples are purchase paths to verify, not claims about current price, stock, ratings, or Amazon reviews.
I weighted the recommendation toward the setup that is easiest to buy correctly. That is why GTR shocks are the default recommendation for most Slash owners, while Pro-Line PowerStroke shocks make more sense for drivers who actually want to tune spring behavior.
What To Check Before Buying Slash Shocks
Before you click any shock listing, check the shock length, pair count, spring situation, oil requirement, and whether your truck is a Slash 2WD, Slash 4X4, VXL, Ultimate, or a modified truck with different suspension parts.
| Check | Why it matters |
|---|---|
| Front vs rear | Slash shock lengths are not all the same. Do not buy four of the same part unless the listing clearly says it is a matched kit. |
| GTR long vs XX-long | The old page text listed 7642. Use the 7462/7462X path for XX-long GTR shocks and a 7461-family part for long GTR shocks. |
| Springs included or separate | Official Traxxas GTR shock pages say springs are sold separately, so confirm whether the Amazon listing includes springs. |
| Oil included or needed | Traxxas lists 30-weight oil with GTR pairs. Horizon/Pro-Line says PowerStroke shocks are pre-assembled and need oil. |
| Pair count | Many shock listings are sold as two shocks, not enough for all four corners. |
| Color/version | Traxxas sells GTR parts in color variants. Color is less important than length, pair count, and fitment. |
Pick Traxxas GTR Shocks For The Easier Slash Upgrade
Traxxas GTR shocks are the better first choice if you want a simpler upgrade that stays inside the Traxxas parts ecosystem. The threaded collars let you adjust preload and ride height without taking the truck apart, and the long/XX-long part paths are easier to explain than a full tuning setup.
Traxxas lists long and XX-long GTR shocks with 13 mm aluminum bodies, PTFE coating, TiN shafts, X-ring sealing, threaded collars, locking lower spring retainers, and 30-weight silicone shock oil. The important catch is springs: Traxxas lists GTR shock pairs as sold without springs, so do not assume a shock-body listing is a complete ready-to-install setup.
Best For
- Slash owners who want the simpler Traxxas parts path.
- Backyard bashers who want threaded preload adjustment.
- Drivers who want clear long and XX-long shock options.
- Readers planning other Traxxas Slash upgrades.
Avoid If
- You want dual-stage spring tuning.
- You do not want to verify spring part numbers.
- The listing does not clearly say long or XX-long.
- The listing hides whether it is one pair or a full four-shock setup.

Buy on AmazonPick Pro-Line PowerStroke Shocks If You Want More Tuning Range
Pro-Line PowerStroke shocks make more sense if you want to tune the suspension rather than just replace weak stock shocks. The dual-stage spring setup uses a shorter upper spring and a longer lower spring, which gives you more ways to change how the truck reacts over rough dirt, corners, and landings.
Horizon/Pro-Line lists PRO606300 front PowerStroke shocks as a direct fit for Slash 2WD and Slash 4X4, with PRO606301 as the rear match. The front product page lists aluminum shock body and cap, 3.5 mm shafts, bladder-sealed caps, molded pistons, dual O-ring seats, and optional spring assortments. It also says the shocks are pre-assembled and need oil.
Best For
- Drivers who like suspension tuning.
- Slash owners who want a front/rear Pro-Line setup.
- Track or rough-surface drivers who want more spring-rate options.
- Readers comfortable checking part numbers before buying.
Avoid If
- You want the lowest-friction buying decision.
- You do not want to add oil or think about spring combinations.
- You are likely to confuse front shocks, rear shocks, spring assortments, and rebuild kits in Amazon search results.
- Your Slash has nonstandard shock mounts and you have not checked whether a mounting kit is needed.

|---|---|---|
| Pro-Line front shocks | PRO606300 | Horizon/Pro-Line lists direct Slash 2WD and Slash 4X4 fit; pair with rear PRO606301. |
| Pro-Line rear shocks | PRO606301 | Confirm the listing is the rear pair, not another front pair. |
| Pro-Line front spring assortment | PRO606303 | Optional tuning part for PRO606300; not required for every driver. |
| Pro-Line rear spring assortment | PRO606304 | Optional tuning part for PRO606301; useful only if you plan to change spring rates. |
| Pro-Line rebuild kit | PRO606302 | Serviceability support, not the first part to buy for a basic upgrade. |
| Traxxas GTR long shocks | 7461 / 7461G / 7461X family | Verify long length, pair count, color/version, and spring requirement. |
| Traxxas GTR XX-long shocks | 7462 / 7462X family | This is the corrected path for the old rear/XX-long shock reference. |
| Traxxas GTR XX-long spring pair | 7449 supplied link | Use as an XX-long spring check only; verify separate spring needs for the long shock position. |
The old live version of this page listed the GTR rear shock as 7642. Treat that as corrected: use the 7462/7462X family for the XX-long GTR shock path, and verify the exact Amazon listing before buying.
Traxxas XX-long GTR springs
7449 Spring, Shock, White GTR Long .767, Black Rate, 5-Pack
Best for: Readers who need a spring check after choosing XX-long GTR shocks
Avoid if: Readers who need a universal spring or oil solution
Use only if 7449 XX-long spring length and rate match the setup; shock oil choice still needs separate tuning judgment.
Buy on AmazonAre Pro-Line Shocks Worth More Than GTR Shocks?
Pro-Line shocks are worth the extra setup attention if you want the dual-stage spring system and plan to tune the truck. If your Slash is mostly a basher and you want an adjustable shock with clear Traxxas support, GTR shocks are the more practical first recommendation.
Do not decide from price alone. Decide from setup appetite. A cheaper or more expensive shock can still be the wrong buy if it is the wrong length, lacks springs you expected, or does not match your Slash model.
What To Do After Installing New Slash Shocks
After installing new shocks, check ride height on a flat surface before making big preload changes. If the truck squats, dives, or rebounds unevenly, make one adjustment at a time so you know what changed.
If you are changing more than shocks, use the broader Traxxas Slash shock upgrade guide before stacking parts. A better Slash servo, tire change, battery change, or gearing change can affect how the truck feels just as much as the shocks. If power setup is part of the plan, check the 2S or 3S LiPo for a Traxxas Slash guide first.
If you are comparing factory-upgraded Slash packages, the Traxxas Slash Ultimate vs VXL comparison can help you decide whether buying the upgraded truck package makes more sense than adding parts one at a time.
FAQ: Pro-Line vs GTR Shocks For The Traxxas Slash
Are Pro-Line or GTR shocks better for the Traxxas Slash?
GTR shocks are better for most Slash owners who want a simple Traxxas-friendly upgrade. Pro-Line PowerStroke shocks are better if you want more spring tuning and are comfortable checking part numbers, oil, and setup details before buying.
What GTR shock part numbers fit a Traxxas Slash?
Check Traxxas GTR long and XX-long shock paths such as 7461/7461G/7461X and 7462/7462X, then verify fitment against your exact Slash model. Do not use the old 7642 reference from the previous page version as the rear shock number.
Do Traxxas GTR shocks include springs?
Many GTR shock listings sell assembled shock pairs without springs. Traxxas pages for GTR shocks say springs are sold separately, so check whether the Amazon listing includes springs or whether you need matching long and XX-long GTR spring pairs.
Do Pro-Line PowerStroke shocks fit Slash 2WD and Slash 4X4?
Horizon/Pro-Line lists PRO606300 front PowerStroke shocks as a direct fit for Slash 2WD and Slash 4X4, and pairs them with PRO606301 rear shocks. Still check the exact Amazon listing because shocks, spring assortments, and rebuild kits can appear together in search results.
Should I buy Pro-Line spring assortments with the shocks?
Not for a simple first upgrade. The spring assortments make sense if you plan to tune spring rates, but they can be a distraction if you mainly need the correct front and rear shock pairs.
Should I replace all four Slash shocks at once?
For a balanced setup, replace shocks as a matched front/rear plan instead of mixing one upgraded corner with old shocks. At minimum, confirm you are buying the correct front pair and rear pair before placing the order.
