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

Stiffer aluminium rear arm for sharper handling

Give your Tamiya GB-01 or GB-01T crisper rear-end feedback with the 3Racing aluminium rear suspension arm in light blue. Manufactured to tighten up the rear geometry, this arm lowers flex during aggressive turns and helps maintain consistent tracking on rough surfaces. It is a straightforward, durable upgrade for weekend trail runs and local club events.

Why aluminium improves rear stability

Aluminium combines low mass with higher rigidity than standard plastic parts. Replacing the stock arms with the 3Racing GB-17/LB reduces unwanted movement under load, improving throttle-on traction and midcorner control. That makes setup changes more predictable when tuning springs and shocks.

Compatibility notes and fitment tips

The GB-17/LB is engineered to match the OEM points on the Tamiya GB-01 and GB-01T chassis. Swap the arms using the original bolts and pins, check clearances after installation, and re-tighten fasteners after the first few runs to settle components.
