Slash 4X4 Front Knuckle Arm Upgrade SLA021 by GPM  [SLA021]

Reinforced alloy knuckle for crisper steering

This pair of alloy front knuckle arms is an aftermarket replacement made for tight fit and minimal play to sharpen steering response on TRAXXAX Slash 4X4 models. The parts mount where the stock knuckles sit and act as direct steering links, preserving the original geometry while reducing slop that softens steering feel.

Fitment note: the knuckles install directly into the front steering assembly, replacing the plastic items without changing servo linkage locations. Because tolerances are close, inspect mount points and steering linkage alignment during fitment to ensure free rotation and full steering travel.

Tuning benefit: exchanging to alloy knuckles keeps pivot points firmer under load and during hard cornering, aiding finer toe and ackermann adjustments by keeping the steering axis stable. They are useful when dialing steering precision for track runs or high-speed trail work.

Fit these alloy knuckles as a direct swap where you want less steering play and a firmer front-end feel, and always confirm fitment and steering travel after installation.
