Rear arm reinforcement for X-MAXX using 6061 T6

This 6061 T6 aluminium rear arm set is an aftermarket replacement made for the TRAXXAS X-MAXX rear suspension. The replacement upper, lower and knuckle arms are machined to reduce flex and help keep suspension motion predictable during aggressive driving or rough terrain.

The kit emphasises rear chassis balance and adjustability: the upper arms have an external adjustable tie-rod connection to set camber and roll response, while the lower arms and knuckles are designed to limit unwanted deformation. POM collars at the knuckle pivots and a steel reinforcement at the centre of the upper arms help keep pivot operation smooth without a large weight increase.

Fitment notes: this is an aftermarket assembly intended for the rear upper and lower arm mounts and rear knuckle positions, fastened with the supplied pins and screws. Rear hub and arm removal is required for fitting; perform clearance and alignment checks after installation to verify intended suspension geometry.

This item is compatible with

  • TRAXXAS XMAXX

Do these replace both upper and lower rear arms?

Yes, the kit replaces the rear upper arms, the rear lower arms and the rear knuckle arms on the X-MAXX rear suspension.

What reinforcement is used inside the arms?

A #45 steel insert is used at the midpoint of the upper arm to add tensile strength while keeping the main body aluminium.

Will these change handling immediately?

Expect a firmer arm feel and reduced flex; you may need to re-tune camber and roll settings to dial in handling after installation.

Are replacement collars available?

The knuckle pivots use POM collars as wear pieces; if you need spares check parts sources for compatible POM collar replacements.

Any advice for testing after fitment?

After fitting, double-check clearances, confirm that arms move freely, then run a short low-speed test before returning to full-power runs.
