This aluminium front upper suspension arm is a scale replacement designed specifically for TAMIYA TL-01, GF-01 and WR-02 chassis. It replaces the factory plastic arm to give a consistent mounting point for the steering knuckle and upper suspension link.
Intended role: use the arm when you require a firmer upper pivot for tuning, improved repeatability in camber and toe, or reduced flex in demanding setups. The part is for chassis tuning and setup adjustments only.
Installation notes: remove the stock arm and move any required bushings or pins across to the new part. Verify clearance at the steering knuckle and shock tower and ensure the servo saver and drive components do not interfere. Tighten mounting hardware to a firm setting and inspect fastener security periodically.
Tuning tips: introduce aluminium arms gradually into your setup and make small incremental changes to toe and camber, testing between adjustments. Because aluminium stiffens the upper mount, review shock valving and spring choices to maintain balanced handling.
