This aftermarket rear knuckle arm is built for the TAMIYA TT02 chassis and comes as a 1 pair set including bearings. Fabricated from aluminium, the piece replaces the OEM plastic knuckle to offer a stronger mounting point for the rear hub and axle.
Compatibility is limited to TT-02 platform variants that share the same rear hub geometry. The supplied ball bearings lower rotational friction at the wheel spindle relative to plain bushings, supporting smoother wheel spin when the car is under load during tuning or practice.
Fitting notes: the replacement installs in the original knuckle position and is compatible with the stock fasteners and axle pin arrangement. Inspect hex screws and pins for wear prior to reassembly, and confirm axle retention and wheel hex engagement after installation. No additional components are normally necessary for a standard TT-02 rear hub fit.
Tuning purpose: the alloy knuckle arm is designed to provide a firmer pivot for rear suspension adjustments, appealing to hobbyists who want a metal upgrade for improved durability and consistent suspension reaction during setup sessions.
Select this aluminium rear knuckle arm when you need a reliable metal replacement for regular tuning, maintenance, or more demanding club use on TT-02 rear hubs.
