Tamiya TT02B Front Knuckle Arm Aluminium TT2B021 Upgrade by GPM  [TT2B021]

Replacement alloy knuckle for TT02B

The aluminium front knuckle arm, model TT2B021, is an aftermarket replacement tailored for Tamiya TT02B scale cars. It substitutes the original plastic knuckle arm and is engineered for direct installation in the front suspension and steering cluster.

The part secures the front wheel hub, attaches to the steering linkages, and delivers steering input from the servo to the wheel. With an alloy construction the knuckle offers a firmer mounting point than stock plastic, which can help preserve alignment under stress and when testing different setups.

Fitment advice: inspect steering pins and bearings for wear before installing, use thread locker on steel screws if needed, and confirm steering geometry after refitting. Minor toe or camber changes may be necessary depending on your link arrangement.

For hobbyists and racers who prefer a metal replacement to the standard plastic parts, this alloy front knuckle arm is a practical upgrade for routine maintenance and setup tuning on TT02B models.
