TRAXXAS SLASH 4X4 Alloy Rear Adjustable Upper Arm by GPM SLA057  [SLA057]

Alloy rear adjustable upper arm

This aftermarket alloy rear adjustable upper arm is produced by GPM for TRAXXAS Slash 4X4 users seeking a direct-replacement, metal upper link for the rear suspension. The part is sold as 1pr and is intended for RC-scale use only, providing a stiffer mounting point compared with typical plastic arms.

Use this arm where you want finer suspension geometry adjustment and more consistent steering feedback at the rear end. The adjustable feature lets you alter linkage length to influence toe and camber settings within the limits of the Slash 4X4 chassis mounting locations, without changing other factory parts.

Installation is straightforward for anyone familiar with basic rear suspension service on Slash vehicles: remove the factory upper arm, transfer any reusable bearings or hardware as required, fit the alloy arm into the existing mounts and check range of motion before final tightening. Do not use this part on full-size vehicles; it is an RC accessory for model tuning and durability improvements.

A practical alloy upgrade for TRAXXAS Slash 4X4 owners who need firmer rear linkage and the ability to fine-tune rear suspension geometry, supplied as one pair for direct replacement.
