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

Alloy front knuckle arm for steering precision

This RC-scale pair of front knuckle arms is an alloy replacement designed for tight fit and minimal play to improve steering response on Slash 4X4 platforms. The parts are intended to sit where stock knuckles fit and act as a direct steering linkage component, preserving existing geometry while reducing slop that can soften steering feel.

Fitment focus: the knuckles are made for direct installation in the front steering assembly, replacing the original plastic pieces without altering servo linkage positions. Because tolerances are close, check mounting points and steering linkage alignment during installation to ensure smooth rotation and full steering travel.

Tuning role: swapping to alloy knuckles helps maintain consistent steering behavior under load and during aggressive cornering, supporting finer toe and ackermann adjustments by keeping pivot points rigid. This makes them useful when dialling steering precision for track or bashing setups.

Use these alloy knuckles as a direct replacement where you need reduced steering play and a firmer front-end feel, while verifying fit and steering travel during installation.
