TRAXXAS SLASH 4X4 Front Adjustable Alloy Upper Arm SLA054 by GPM  [SLA054]

Adjustable alloy upper arm for TRAXXAS SLASH 4X4 front end

Designed as an aftermarket metal alternative, this front adjustable upper arm fits TRAXXAS SLASH 4X4 chassis and is supplied as a pair. The SLA054 uses alloy construction to deliver a firmer mounting point and a single adjustment pivot to change static camber and roll center without replacing other suspension components.

Installation uses the factory hinge pin and ball-stud locations for a direct swap with the stock plastic arms, so standard hardware can usually be reused. If you plan to change geometry or increase durability, consider hardened hinge pins or upgraded ball studs; major trimming of nearby links is not typically required on standard Slash 4X4 setups.

On track, the alloy arm reduces flex under load and helps keep camber and toe settings consistent between runs. Adjust settings incrementally and watch for shifts in steering balance and tyre wear as you move away from stock geometry.

This upgrade part provides a stronger front upper arm for setup work and repeatable handling on the Slash 4X4 platform, aimed at hobbyists wanting metal durability.
