TRAXXAS X-Maxx Adjustable Upper Arm and Supporting Mount - TXM054SN by GPM  [TXM054SN]

Robust supporting mount and upper arms

This aftermarket supporting mount and upper arm set is made for TRAXXAS X-Maxx platforms as a tunable replacement part. The assembly pairs #45 spring steel with aluminium and machined components to give strength where heavy-scale runs demand it while keeping weight managed for predictable handling.

The kit offers direct tie-rod length adjustment via a central hole; a small pin or hex key fits the bore to alter tie-rod length and the stabilising mount provides staged support for those settings. That lets you tune camber and toe quickly for varied terrain or track surfaces without taking the suspension apart.

Fitting is straightforward for builders familiar with X-Maxx suspension: remove the factory upper arms and supporting mount, reuse compatible fasteners where applicable, and confirm linkage geometry after each tweak. The parts are intended to work with standard hobby servos, motors, ESCs and X-Maxx suspension hardware with no chassis modification.

The design focuses on functional tuning points rather than cosmetic trim, giving clear adjustment positions for drivers aiming to refine handling or drift balance in scale driving.

Fit this GPM mount and upper arm set to add adjustable linkage and a more robust support option to X-Maxx 6S/8S builds, keeping setup changes quick at the track.
