Tamiya TT02 Rear Knuckle Arm Stiffener TT2022 by GPM  [TT2022]

TT02 rear knuckle alloy upgrade

The TT2022 alloy rear knuckle arm is an aftermarket replacement built for the Tamiya TT02 platform. As an aluminium component it provides a firmer mounting point at the rear wheel hub, useful for tuning rear steering geometry and altering suspension behaviour on electric TT02 models.

Fitment uses the factory TT02 rear hub location and the vehicle's original mounting points and fasteners. When swapping in the knuckle, verify clearance and alignment before final tightening, then inspect rear wheel alignment and suspension travel as part of setup. The upgrade aims to deliver a predictable change in rear steering feel for hobbyists refining handling at the track or during backyard sessions.
