GPM Racing Alloy Rear Knuckle Arm with Bearing - 1PR Set for Tamiya TT02 (TT2022B)

Precision rear knuckle for TT02 applications

This aftermarket rear knuckle arm is produced to fit the TAMIYA TT02 chassis and is supplied as a 1 pair set with bearings. CNC machined from aluminium, the component replaces the OEM plastic knuckle to provide a rigid mounting point for the rear hub and wheel axle assembly.

Compatibility is aimed at TT-02 platform variants that utilise the same rear hub geometry. The preinstalled ball bearings lower rotational friction at the wheel spindle compared with plain bushings, aiding smoother rotational inertia under load during setup and testing.

Assembly notes: the part locates in the stock knuckle position and is designed for use with the original fasteners and axle pin layout. Verify condition of hex screws and pins and ensure correct axle retention and wheel hex engagement after installation. No additional specialised hardware is required for standard TT-02 rear hub installations.

Performance intent: this CNC aluminium knuckle arm provides a firmer pivot for rear suspension geometry adjustments, offering improved durability and stable suspension response for precision hobbyist builds and demanding practice sessions.

What machining tolerances are typical for this part?

The component is produced to hobby-grade CNC tolerances appropriate for aluminium upgrades; check bearing fit and fastener seating during initial assembly to ensure correct alignment.

Are bearings preinstalled to specification?

Bearings are supplied with the knuckle and positioned for the wheel spindle locations. Confirm bearing orientation and secure retention during installation.

Does aluminium affect suspension compliance?

Aluminium increases pivot stiffness relative to plastic parts, which reduces play and yields more consistent suspension geometry under load; tune damping and spring rates accordingly.

What checks should I do after fitting?

Verify hardware torque, bearing smoothness, axle retention and wheel hex engagement. Reinspect after a short test run and retorque if necessary. Write Product Review Please sign in your account before you can write any review. Sign In Close
