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

Adjustable alloy upper arm for rear suspension

This aftermarket alloy rear adjustable upper arm is an OEM-fit replacement for TRAXXAS Slash 4X4 owners who want a metal upper link to stiffen the rear mounting point. The part ships as 1pr and is intended for RC-scale use, offering firmer support than stock plastic arms.

Use this adjustable arm to dial in rear toe and camber with finer increments than fixed-length links allow, staying within the Slash 4X4 chassis mounting limits and without altering other factory components.

Installation is straightforward for anyone accustomed to rear suspension work on Slash models: remove the factory arm, transfer any reusable bearings or fasteners, fit the alloy arm into the existing mounts and check travel before final torque. This is an RC upgrade only and must not be used on full-size vehicles.

A practical alloy swap for Slash 4X4 drivers who want a firmer rear linkage and simple suspension tuning, supplied as one pair for direct replacement.
