3RACING 3RAC-HKS30/LB Light Blue 3.0mm Aluminium Single Servo Arm  [3RAC-HKS30/LB]

Steering precision upgrade for 3RACING 3RAC-HKS30/LB

The 3RACING 3.0mm Aluminium Single Servo Arm for Ko Propo and Sanwa systems gives hobbyists a robust option when swapping out stock plastic arms. The light blue anodised finish looks neat on the servo spline while helping resist wear over regular club runs.

Use cases on track and around town

This arm is well suited to drivers who want firmer steering input and reduced movement at the wheel. Its aluminium build delivers stability for both close racing and casual practice sessions without adding complexity to your setup.

Fitment notes and simple install

Designed to match common Ko Propo and Sanwa servo splines, the arm installs quickly and aligns cleanly with existing linkages. Basic tools are all you need to swap it in and get back on the road.
