Tamiya TL-01/GF-01/WR-02 Aluminum Rear Lower Suspension Arm Upgrade - TL01-13303-LB by Jazrider  [TL01-13303-LB]

Tuning benefits of an aluminum lower arm

This aluminum rear lower suspension arm is designed for Tamiya TL-01, GF-01 and WR-02 chassis and comes in a light blue anodized finish. As a direct replacement for the stock plastic arm, the machined component reduces local compliance and stabilises the rear mounting point for more predictable handling on tuned touring and drift cars.

Installation is straightforward for experienced builders: remove the factory rear lower arm, check hinge pin condition and mount integrity, fit the aluminium unit and cycle the suspension to ensure clearance. Replace the other side afterwards and reconfirm wheel alignment and toe settings to suit your setup.

Tuning advice: fitting this aluminum arm tightens the rear end feel by lowering compliance at the mount, which tends to produce crisper turn-in and firmer mid-corner traction. This affects transient responses more than ride height, so adjust shock positions, damping and toe to fine tune balance after installation.
