This 4 piece aluminium ball end set is manufactured as a durable upgrade for the front and rear upper arm connections on a 1/10 TRAXXAS Rustler VXL. They replace softer stock fitted components to deliver a firmer interface at each linkage pivot.
In technical terms, the alloy contact surface minimises play at the upper arm seat which helps maintain suspension geometry under dynamic loads and improves the predictability of setup changes. These parts are intended as precision aftermarket upgrades for scale chassis use.
Fitting requires routine upper arm removal and verification of ball stud seating. Confirm thread engagement and torque specifications before returning the vehicle to service.
A precision-focused retrofit to improve upper arm link stiffness and repeatability on the Rustler VXL platform.
