The 3Racing GB-11/LB is an aluminium rear shock tower engineered for the Tamiya GB-01 chassis. It provides a rigid mounting platform that helps transmit suspension inputs cleanly to the chassis, aiding precise setup work.
By replacing the standard plastic tower with aluminium, teams and serious hobbyists gain a stable reference point for damping and spring adjustments. This consistency helps isolate suspension changes and speeds setup iteration.
Manufactured to match GB-01 fixings, the GB-11/LB fits without major modification and allows competitors to move quickly from stock to a metal rear mount when preparing for events.
