Tamiya TT02B Alloy Front Knuckle Arm by GPM TT2B021  [TT2B021]

Front knuckle arm for TT02B

This aluminium front knuckle arm from GPM (TT2B021) is an aftermarket replacement part intended for use on Tamiya TT02B scale RC cars. It replaces the stock plastic knuckle arm and is designed to serve as a direct-fit suspension steering component within the model's front assembly.

The part's role is purely within the RC chassis: it locates the front wheel hub, connects the steering linkages, and transfers steering inputs from the servo to the wheel. The alloy construction aims to provide a firmer mounting point compared with original plastic parts, which can help maintain alignment under load and when experimenting with setup changes.

Installation notes: inspect existing hardware and ball bearings for wear before fitting, use thread locker on steel screws if required by your chassis setup, and verify steering geometry after installation. Minor toe or camber readjustment may be needed depending on the steering links used.

For hobbyists maintaining or tuning a TT02B, this GPM alloy front knuckle arm provides a metal alternative to standard plastic parts, suitable for straightforward replacement and routine chassis setup work.
