Traxxas Slash Shocks Or Servo First?

Short answer: upgrade Traxxas Slash shocks first if the truck bottoms out, bounces, leaks shock oil, lands poorly, or cannot stay planted over rough ground. Upgrade the steering servo first if the wheels will not center, the servo is weak, gears are stripped, or steering fades under load. If both are worn out, fix steering slop and shock condition before adding more speed.

Choose Shocks First For Landing And Bumpy Terrain Problems

Shocks make the truck easier to control over bumps, jumps, rough dirt, and uneven grass. If the Slash rebounds like a pogo stick, leaks oil, or slaps the chassis after every landing, a servo will not solve that.

Big Bore shocks are the simpler set-of-four Traxxas path. GTR shocks are the more premium Traxxas-style route, but you need to pay attention to long and XX-long length, springs, oil, and pair quantity. For a deeper suspension page, use the Traxxas Slash shock upgrade guide and Pro-Line vs GTR shocks.

Choose A Servo First For Steering Problems

A stronger servo makes sense when the stock servo is weak, stripped, inconsistent, or slow to return to center. But do not use a new servo to hide binding. Check the steering bellcrank, servo saver, links, hubs, and front suspension before assuming the servo is the only problem.

For a part-by-part comparison, use the best servo for the Traxxas Slash guide. Match the servo spline and servo saver before adding a metal horn or high-torque servo.

Do Not Add 3S Power To A Loose Truck

A Slash that already wanders, bounces, or lands poorly will not become easier to drive just because it is faster. If you plan to run more power, fix steering and suspension first. More speed makes weak shocks, tired tires, loose links, and stripped servo gears more obvious.

If your upgrade plan includes batteries, read 2S vs 3S LiPo battery and RC battery connector types before buying packs.

Where This Fits In A Full Slash Upgrade Plan

If you are rebuilding the whole truck, use Traxxas Slash upgrades as the hub. If you are choosing between factory-upgraded trucks instead of upgrading a basic Slash, compare Traxxas Slash Ultimate vs VXL.

FAQ

Should I upgrade Slash shocks or servo first?

Upgrade the part causing the symptom. Shocks fix bouncing, leaking, and landing control. A servo fixes weak, stripped, or inconsistent steering after you confirm the linkage is not binding.

Will a better servo make my Slash handle better?

Only if steering torque, centering, or stripped gears are the problem. A servo will not fix bad tires, poor shock setup, or loose suspension parts.

Are GTR shocks better than Big Bore shocks?

GTR shocks are the more tunable Traxxas path, but Big Bore shocks are simpler as a set-of-four upgrade. Check length, springs, oil, and model fit before buying either one.
