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

Alloy front knuckle for TT02B handling

This aluminium front knuckle arm, model TT2B021, is an aftermarket replacement designed for Tamiya TT02B scale RC cars. It takes the place of the original plastic knuckle arm and is produced to fit directly into the front suspension and steering assembly.

The component locates the front wheel hub, links to the steering rods, and transmits steering inputs from the servo to the wheel hub. The alloy construction provides a firmer mounting point than stock plastic, helping to hold alignment during heavier cornering and while testing setup changes.

Installation notes: check existing fasteners and bearings for wear before fitting, apply thread locker to steel screws when appropriate for your setup, and recheck steering geometry after installation. Small toe or camber adjustments may be needed depending on the steering link configuration.

For tuners and club racers working on TT02B cars, this alloy front knuckle arm gives a metal option to replace plastic parts and supports routine chassis setup and maintenance, offering more predictable steering behaviour than stock components.
