This rear knuckle arm is an RC-scale replacement machined from 6061-T6 aluminium for TRAXXAS MAXX platforms and is intended to replace the factory plastic knuckle to provide a stiffer mounting point for the rear suspension and hub while preserving original geometry.
Design features include pressed Delrin collars at the mounting bores to reduce play between knuckle and hub pins and a CNC-machined profile to control weight and maintain alignment. The item is supplied as a two piece set for the rear locations.
During installation verify pin and fastener orientation against your vehicle manual, check wheel-bearing preload after assembly, and confirm clearance between hub hardware and knuckle before full-speed testing. Because this part changes rear stiffness, re-check toe and tracking after initial runs and adjust links or turnbuckles for balanced handling.
Fit this pair to reduce rear hub flex and improve mount rigidity for links and hubs; always verify and fine tune alignment after fitting.
