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

Aftermarket aluminium upper arms for X-Maxx

These aluminium front and rear upper arms are intended as a direct aftermarket swap for the TRAXXAS 1/8 X-Maxx. Supplied as one pair, they replace the OEM upper arms to stiffen the suspension link mounts and reduce flex when the model is driven aggressively.

Practically, the added stiffness changes camber and toe behaviour on compression which can affect steering character and cornering balance. Installation normally uses the original mounting pins and hardware, so no chassis-level changes are required to fit the arms to the X-Maxx chassis.

Maintenance follows the usual routine for suspension arms: inspect pivot holes and ball-stud seats for wear and recheck torque after early runs. Small burrs or light surface oxidation can be cleaned off before installation.

For hobbyists wanting a durable, stiffer upper arm for the X-Maxx, this aluminium pair is a straightforward upgrade that tightens suspension feel and helps maintain consistent handling.
