TAMIYA TT02 Rear Knuckle Arm Bearing Upgrade - TT2022B by GPM  [TT2022B]

Aluminium rear knuckle for TT02 hubs

This aftermarket rear knuckle arm is made for use on the TAMIYA TT02 chassis and supplied as a 1 pair set with bearings. Manufactured from aluminium, the component replaces the standard plastic knuckle to provide a firmer mounting point for the rear hub and wheel axle assembly.

Fitment is specific to TT-02 platform variants that share the same rear hub geometry. The included ball bearings cut rotational friction at the wheel spindle compared with plain bushings, which helps preserve smoother wheel spin under load during tuning and practice laps.

Installation notes: the part fits into the stock knuckle location and uses the original fasteners and axle pin layout. Inspect existing hex screws and pins for wear before reassembly, and confirm wheel hex engagement and axle retention after fitting. No extra parts are normally required beyond the standard TT-02 rear hub hardware.

Tuning role: this alloy knuckle arm gives a firmer pivot for rear suspension adjustments. It suits hobbyists seeking a metal replacement for improved durability and repeatable suspension response during setup changes.

Choose this aluminium rear knuckle arm when you want a stronger metal alternative for routine maintenance, frequent tuning, or tougher club use in TT-02 rear hub assemblies.
