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

Rear Knuckle for TT01 Series

This alloy rear knuckle arm with collars is an aftermarket replacement made for the Tamiya TT01 chassis and carries part number TT022. It replaces the OEM knuckle to give a stiffer mounting point for rear hubs and collars while maintaining the TT01 mounting footprint.

The component functions as a rear suspension linkage part that helps hold wheel alignment and axle position steady under load. Collars supplied with the arm locate the hub and ensure the correct axle spacing, supporting consistent handling during tuning sessions.

Installation follows conventional TT01 rear knuckle replacement steps: remove the original knuckle, transfer the hubs, pins and hardware, then fit the new arm. Examine mating faces and fasteners for wear and confirm wheel alignment and free rotation after installation.
