Replace the stock rear arms on your Tamiya GB-01 or GB-01T with the 3Racing light blue aluminium unit to gain better steering feel and reduced flex. The alloy design maintains a low mass while providing a firmer platform for suspension tuning, helping your setup remain consistent under load.
The GB-17/LB delivers increased stiffness where it matters while keeping overall weight modest. That improves feedback through corners and supports finer suspension adjustments, which is useful when refining camber and toe settings for faster lap times.
The part is precision made to align with the Tamiya GB-01 and GB-01T mounts, so you can fit it using the original hardware. Check pin retention and clearances after the first runs and retorque fasteners to maintain reliability.
