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

Rear Knuckle Arm Upgrade for TT01

This alloy rear knuckle arm with collars is an aftermarket replacement for the Tamiya TT01 chassis, sold as part TT022. It replaces the stock rear knuckle to provide a firmer mounting point for the rear hubs and collars while preserving the original TT01 mounting pattern.

As a rear suspension linkage, the component helps keep wheel alignment and axle position consistent under load. The supplied collars locate the hub and maintain correct spacing on the axle assembly, aiding repeatable handling adjustments during setup and tuning.

Installation follows standard TT01 rear knuckle replacement steps: remove the original component, transfer wheel hubs, pins and associated hardware, then fit the new arm. Inspect mating surfaces and fasteners for wear during installation and verify wheel alignment and free rotation after fitting.
