TRAXXAS MAXX Monster Truck Aluminum Rear Knuckle Arm by GPM TXMS022  [TXMS022]

Aluminum rear knuckle arm for MAXX

This rear knuckle arm is an RC-scale replacement part machined from 6061-T6 aluminum and produced for TRAXXAS MAXX platforms by GPM. The component replaces the standard plastic knuckle to provide a stiffer mounting point for the rear suspension and wheel hub while retaining standard geometry.

Design details include pressed Delrin collars at the mounting bores to reduce play between the knuckle and hub pins, and a CNC-machined streamline profile to control weight and maintain alignment. The part is supplied as a 2 pcs set intended to fit the rear location of the chassis.

On installation, verify pin and fastener orientation against your vehicle manual, check wheel-bearing preload after assembly, and confirm clearance with calipers and hub hardware before full-speed testing. This component affects rear toe and tracking stability, so re-check alignment after initial runs and adjust link lengths or turnbuckles as required for handling balance.

Use this pair to reduce flex at the rear hub and to provide a firmer mount for links and wheel hubs; perform alignment checks after fitment to tune handling response.
