Tamiya TT01 Alloy Rear Knuckle Arm with Collars by GPM TT022  [TT022]

TT01 Rear Knuckle Arm

This alloy rear knuckle arm with collars is an aftermarket replacement designed for the Tamiya TT01 chassis, offered under GPM part TT022. It replaces the stock rear knuckle arm to provide a more rigid mounting point for the rear hubs and collars while maintaining the original TT01 mounting pattern.

Functionally the piece serves as a rear suspension linkage component, keeping wheel alignment and axle positioning consistent under load. The included collars help locate the hub and maintain correct spacing on the axle assembly, which supports repeatable handling adjustments during setup and tuning.

Installation follows standard rear knuckle replacement steps for TT01 variants, removing the original part and transferring wheel hubs, pins, and associated hardware. Inspect mating surfaces and fasteners for wear during installation and verify wheel alignment and free rotation after fitting.
