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

Front alloy adjustable upper arm for TRAXX 4X4

This aftermarket alloy upper arm is supplied as a pair for TRAXXAS SLASH 4X4 owners seeking a metal alternative to the stock plastic arms. The SLA054 gives a single adjustment point to tune camber and roll center while relying on existing suspension geometry.

Swap is straightforward using the factory hinge-pin and ball-stud positions, so most users can reuse original hardware. For those upgrading durability or altering geometry, consider compatible hardened pins or different ball studs to suit your setup; major cutting of nearby links is not normally required.

In practice, the alloy arm limits flex at the mounting point and helps maintain consistent camber and toe settings run-to-run, which is useful for repeatable setup testing. Make measured changes and observe steering feedback and tyre wear after each adjustment.

A solid drop-in alloy upgrade for front-end tuning on the Slash 4X4, suited to hobbyists who prefer metal components for setup consistency.
