TRAXXAS 1/8 X-Maxx Aluminium Front/Rear Upper Arms by GPM TXM054F/R  [TXM054F/R]

Aluminium front/rear upper arms for X‑Maxx

These aluminium front and rear upper arms are a direct aftermarket replacement designed for the TRAXXAS 1/8 X-Maxx platform. Sold as one pair, the parts replace the factory upper arm components to provide a stiffer mounting point for the suspension links and to reduce flex under load.

In practical setup terms these arms serve as a tuning lever: increased rigidity alters camber and toe behaviour under compression, which can change steering feel and cornering balance. Installation typically reuses the stock mounting hardware and pins, so no chassis- or gearbox-level modifications are required when fitted to the intended X-Maxx chassis.

Maintenance is the same as for standard suspension arms: inspect mounting holes and ball-stud interfaces for wear, and confirm fastener torque after the first run. Because the parts are aluminium, minor burrs or surface oxidation can be addressed with light cleaning before installation.

For model builders seeking a stiff, replacement upper arm option for the X-Maxx platform, this GPM aluminium pair provides a simple hardware swap that targets suspension rigidity and consistent handling response.
