TAMIYA TL-01/GF-01/WR-02 Aluminum Front Upper Arm for Tuning JR-TL100-BK by Jazrider  [JR-TL100-BK]

Scale aluminium upper arm compatible with TAMIYA TL-01/GF-01/WR-02

This aluminium front upper suspension arm is manufactured as a direct-fit replacement for the TAMIYA TL-01, GF-01 and WR-02 chassis. It replaces the original plastic upper arm to provide a firmer mounting point for steering and the upper suspension link.

Intended role: choose this arm when you want to cut down on upper-link flex in aggressive driving or competitive tuning, and to achieve more consistent steering geometry after repeated runs. The part is intended for setup-level changes rather than structural chassis modifications.

Installation notes: remove the factory arm, transfer any required bushings or locating pins, and check the match at the steering knuckle and shock tower. Verify clearance to the servo saver and drive components, then tighten hardware to a firm torque without overdriving. Inspect fasteners after the first running session.

Tuning tips: fit aluminium components incrementally and evaluate handling between small setup changes. Because aluminium stiffens the upper pivot, you may need to soften shocks or alter spring rates to preserve predictable balance.
