TRAXXAS X-Maxx Upper Arms and Support Mount for Tuning - TXM054SN by GPM  [TXM054SN]

Adjustable support and upper link kit

This aftermarket support mount and upper arm assembly fits TRAXXAS X-Maxx platforms as a purpose-built tuning replacement. It uses #45 spring steel paired with aluminium to resist collapse on heavy impacts while remaining light enough for sensible suspension dynamics.

Tuning is simplified by a central adjustment hole that accepts a small pin or hex key to change tie-rod length, with the stabiliser mount offering stepped support for set positions. These features let you dial in camber and toe for different surfaces without full disassembly.

Installation suits enthusiasts familiar with the X-Maxx suspension layout: remove the stock upper arms and supporting mount, reuse compatible fasteners where possible, and recheck link geometry after each adjustment. The components are compatible with hobby servos, ESCs and motors used in X-Maxx builds without trimming the chassis.

The emphasis is on practical tuning points rather than show finishes, giving straightforward adjustments for drivers refining handling or slide behaviour.

Use TXM054SN to add adjustable linkage and a stiffer mounting option to X-Maxx 6S/8S rigs, keeping setup changes accessible trackside.
