6061 T6 aluminium rear arm replacement for X-MAXX

This aluminium rear arm set is an RC-scale replacement built for the TRAXXAS X-MAXX rear suspension. The kit swaps the rear upper arms, lower arms and knuckle arms for machined aluminium components aimed at improving structural strength and keeping arm movement consistent during heavy bashing or high-speed runs.

The parts concentrate on rear chassis control and tuning: the upper arms feature an externally adjustable tie-rod style connection to tune camber and roll-center, while the lower arms and knuckles are shaped to cut down unwanted flex. POM collars at knuckle interfaces and a steel insert in the upper-arm midpoint help retain smooth pivot motion without a large weight penalty.

Installation note: this is an aftermarket accessory that fits the rear upper and lower arm positions and rear knuckle locations, secured with the supplied pins and screws. Basic removal of the rear hub and arm mounts is required; check range of motion and chassis alignment after fitting to confirm the intended suspension geometry.

Which rear parts does this TXM545522 kit replace?

It replaces the rear upper arms, rear lower arms and the rear knuckle arms at the rear suspension mounting points on the X-MAXX.

What are the primary materials used in the arms?

The main bodies are machined from 6061 T6 aluminium with a #45 steel reinforcement in the upper arm center, POM bushings at knuckles, and stainless steel fasteners.

Are the upper arms adjustable for alignment?

Yes. The upper arms use an adjustable tie-rod style joint to allow small changes in effective arm length for camber and roll-center tuning.

The kit includes the pins and screws needed to mount the arms and knuckles; confirm the contents against the parts list before starting installation.

Any setup tips after fitting these arms?

After fitting, inspect arm travel and clearances, recheck suspension preload and camber, then perform a controlled test run before full-speed use.
