This rear knuckle arm is an RC-scale replacement machined from 6061-T6 aluminum for TRAXXAS MAXX platforms, intended to replace the standard plastic knuckle and provide a firmer mounting point for the rear suspension and wheel hub while keeping stock geometry.
Construction highlights include pressed Delrin collars in the mounting bores to reduce clearance between knuckle and hub pins, plus a CNC-machined streamlined section to manage mass and alignment. The part ships as a 2 piece set for the rear positions.
On installation verify pin and fastener orientation per your chassis manual, check bearing preload after assembly, and confirm hub clearance before initial high-speed runs. This upgrade can alter rear stiffness and handling, so re-check toe and tracking and tune link lengths or turnbuckles as needed.
Install this set to reduce rear hub flex and secure link mounting; perform alignment checks to refine handling after fitment.
