TAMIYA TT02 Rear Knuckle Arm with Bearing by GPM TT2022B  [TT2022B]

Rear knuckle arm for TT02

This aftermarket rear knuckle arm is produced by GPM for use on the TAMIYA TT02 chassis and supplied as a 1 pair set with bearings. Built from aluminium, the part replaces the OEM plastic knuckle to provide a stiffer mounting point for the rear hub and the wheel axle assembly.

Fitment is specific to TT-02 platform variants that use the same rear hub geometry. The included ball bearings reduce rotational friction at the wheel spindle compared with a plain bushing installation, helping maintain smoother wheel spin under load during tuning sessions.

Installation notes: the part installs in the same location as the stock rear knuckle arm and uses the original fasteners and axle pin layout. Check existing hex screws and pins for wear before reassembly, and verify wheel hex engagement and axle retention after fitting. No additional parts are required beyond what is normally used on a TT-02 rear hub setup.

Tuning role: this alloy knuckle arm is intended to provide a firmer pivot for rear suspension geometry adjustments. It is suitable for hobbyists who want a metal replacement for durability and consistent suspension response during setup changes and track practice.

Choose this GPM aluminium rear knuckle arm when you need a metal replacement for routine maintenance, tuning iterations, or higher durability in TT-02 rear hub assemblies.
