Precision Steering Upgrade with 3RACING 3RAC-HKS26/SI

The 3RACING 2.6mm Aluminium Single Servo Arm is engineered for Ko Propo and Sanwa servos to improve steering feel and repeatability. This silver arm is a straightforward, durable swap for hobbyists wanting tighter control on paved tracks and club events.

Benefits of an Aluminium Servo Arm

Aluminium delivers higher stiffness and better wear resistance than stock plastic arms. The 3RACING 3RAC-HKS26/SI reduces flex under load, giving more predictable steering response during aggressive cornering and long race runs.

Fitment and Typical Use

Designed specifically for Ko Propo and Sanwa systems, installation is simple with standard servo splines. The arm suits touring cars and on-road builds where precise steering and consistent feedback are priorities.
