This GPM rear lower arm set is made from precision-machined alloy to replace the stock plastic pieces on the Traxxas 1/10 Rustler VXL. The construction focuses on increased structural rigidity to reduce flex under load while maintaining accurate fitment to factory mounting points. The alloy finish helps preserve suspension geometry during sustained use.
Installers should verify linkage alignment and inspect existing pivot hardware for wear before reusing it. Because these arms reduce flex, small adjustments to shock settings and toe may be required to optimise handling for competition or heavy off-road use.
