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

Precision 7075 rear upper arm for Mini XRT upgrades

This machined 7075 aluminium rear upper suspension arm fits the TRAXXAS MINI XRT VXL 3S as a direct upgrade to the OEM plastic link. The CNC-quality aluminium reduces deformation at the hub mount and preserves upper-link alignment under dynamic load, improving repeatable rear geometry during acceleration and cornering.

Installation uses standard rear arm replacement steps: locate the arm in the rear upper mount, insert the specified 34.2mm outer pin through the arm and hub carrier, and secure with the supplied M3 lock nut. The package supplies both arms with the matching pins and lock nuts to simplify fitment on the compatible chassis.

As a tuned component, the arm supports adjustments to rear roll centre and link stiffness when used alongside shock and link upgrades, offering a measurable reduction in unwanted movement at the hub carrier.

Choose this CNC-friendly 7075 arm when precise, low-deflection rear upper link mounting is required for competitive tuning and reliable handling under load.
