TRAXXAS MINI XRT VXL 3S Rear Upper Arms 7075 Alloy Upgrade - XRTM057 by GPM  [XRTM057]

7075 aluminium rear upper arm for Mini XRT

This rear upper suspension arm is CNC-style 7075 aluminium made for the TRAXXAS MINI XRT VXL 3S to replace the standard plastic link. The stronger alloy construction keeps the rear hub stub axle carriers better aligned under load and lowers unwanted movement where the upper link attaches to the hub.

Fitting is straightforward: position the rear upper arm into the mounting slot, insert the outer 34.2mm arm pin through the arm and hub carrier, then tighten the supplied M3 lock nut. The kit ships with both arms plus the outer pins and lock nuts so the unit installs without sourcing additional fasteners on the compatible chassis.

As a tuning part, the arm helps deliver a firmer rear response during throttle and when cornering, and it can be used alongside link geometry or shock changes to refine rear roll behaviour.

Fit these aluminium rear upper arms when you want reduced hub carrier flex and a predictable rear-end feel while retaining simple installation using the included hardware.
