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

Performance-oriented aluminium upper arms for X-Maxx

These aluminium front and rear upper arms are an aftermarket replacement tailored for the TRAXXAS 1/8 X-Maxx. Supplied as a pair, they substitute the factory arms to increase rigidity at the suspension link mounts and reduce unwanted flex under load.

As a tuning item, the extra stiffness alters camber and toe behaviour when the suspension compresses, which can influence steering precision and cornering balance. Fitting typically reuses the original pins and mounting hardware, so no structural changes to the chassis or gearbox are needed for installation on the X-Maxx chassis.

Care and inspection match standard arms: monitor mounting holes and ball-stud contact areas for wear, and confirm fastener torque after the initial run. Address any light surface oxidation or burrs on the aluminium with simple cleaning before assembly.

For modelers seeking a tougher replacement arm for the X-Maxx, this aluminium pair is a direct swap that sharpens suspension rigidity and promotes repeatable handling.
