TRAXXAS X-Maxx Spring Steel and Aluminum Supporting Mount with Front/Rear Upper Arms by GPM TXM054SN  [TXM054SN]

Supporting mount and upper arms

This is an RC-scale supporting mount and upper arm set designed for TRAXXAS X-Maxx platforms, provided as an aftermarket replacement and tuning part by GPM. The assembly uses #45 spring steel combined with aluminum to balance strength and weight while resisting collapse under load common in heavy-scale runs.

The kit allows direct adjustments to tie-rod length and wheel angle through a center adjustment hole; a small pin or hex key can be inserted to change tie-rod length and the stabilizing mount is adjustable to support those settings. These features let you tune camber and toe for different track or terrain conditions without major disassembly.

Installation is straightforward for users familiar with X-Maxx suspension layouts: swap the original upper arms and securing mount, retain existing fasteners where applicable, and verify linkage geometry after each adjustment. The components are intended to work with hobby-grade servos, motors, ESCs, and standard X-Maxx suspension hardware without modification.

The design emphasizes tuning flexibility over decorative features, providing discrete adjustment points for setup changes aimed at improved handling or drift characteristics in RC-scale driving.

Use this GPM mount and upper arms to add adjustable linkage and a stronger mounting option to X-Maxx 6S/8S setups, keeping adjustments accessible for on-track tuning.
