The 3RACING 3.0mm Aluminium Single Servo Arm designed for Ko Propo and Sanwa systems replaces weaker plastic arms with a more durable aluminium option. The light blue anodised finish keeps the look tidy while resisting everyday wear.
Perfect for racers and hobbyists who want a firmer steering input, this arm helps maintain alignment under load and reduces unwanted flex during aggressive driving or repeated use.
Made to suit common Ko Propo and Sanwa servo splines, the arm is a straightforward swap. Centre the servo and confirm link lengths after fitting to ensure accurate steering geometry.
