3Racing GB-17/LB Light Blue Aluminum Rear Suspension Arm for Tamiya GB-01/GB-01T  [GB-17/LB]

Precision aluminum rear arm for improved control

Improve handling on your Tamiya GB-01 or GB-01T with the 3Racing aluminum rear suspension arm in light blue. This replacement part is machined to reduce flex while keeping weight low, giving more consistent steering and better response on paved and mixed surfaces. The alloy construction resists wear under frequent running, extending the service life of your rear end.

Benefits of switching to alloy arms

Aluminum provides a clear balance of stiffness and weight compared to stock plastic arms. Upgrading to the 3Racing GB-17/LB helps reduce unwanted deflection during cornering and improves repeatable geometry for lap after lap consistency. That makes it a practical upgrade for club racers and weekend drivers alike.

Fitment and simple installation

The GB-17/LB is built to match the OEM mounting points for the Tamiya GB-01 and GB-01T, so installation is straightforward using your existing hardware. Basic hand tools are all you need to swap the rear arms, and the part is suitable for users who want a quick, reliable upgrade.
