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

Race-focused aluminium rear arm for tuning consistency

The 3Racing GB-17/LB rear suspension arm provides a rigid, lightweight replace­ment for the Tamiya GB-01 and GB-01T chassis. Machined to tight tolerances, the alloy arm reduces compliance at the rear suspension pivots so setup changes produce repeatable on-track results. The light blue anodised finish adds corrosion protection while keeping the part identifiable during setup work.

Technical benefits for competitive setups

Using aluminium reduces elastic deformation seen in standard plastic arms, which improves roll centre stability and helps maintain consistent toe and camber under load. That stability allows finer shock and spring adjustments and aids drivers seeking predictable handling through fast sweepers and rapid direction changes.

Installation, fit, and tuning notes

The GB-17/LB matches OEM mounting points for straightforward installation with existing hinge pins and fasteners. For race preparation, inspect pivot fit and apply a thin film of low-viscosity grease to the hinge area to minimise stiction. After initial runs, remeasure toe and camber to confirm setup values remain within specification.
