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

Aluminium upper arms for X-Maxx upgrade

These aluminium front and rear upper arms are an aftermarket replacement made for the TRAXXAS 1/8 X-Maxx platform. Supplied as one pair, the parts replace the stock upper arms to give a firmer mounting point for suspension links and reduce flex when running hard.

From a setup point of view, the increased stiffness changes camber and toe behaviour under compression, which can alter steering response and cornering balance. Fitting normally uses the original pins and hardware, so you do not need to modify the chassis or gearbox to install the arms on the intended X-Maxx chassis.

Service is the same as standard arms: check mount holes and ball-stud interfaces for wear and retorque fasteners after the first outing. As these are aluminium, address any small burrs or light surface oxidation with a quick clean before assembly.

For builders after a stiffer replacement upper arm for the X-Maxx, this aluminium pair gives a straightforward hardware swap to sharpen suspension rigidity and help preserve consistent handling.
