The 3RACING 3.0mm Aluminium Single Servo Arm for Ko Propo and Sanwa systems blends durability with a tidy light blue anodised look. It is a practical upgrade for model owners wanting a firmer feel from their steering setup.
Ideal for hard-packed tracks and gravel practice, the aluminium construction helps the linkage resist flex under load. It suits drivers who want consistent control without frequent part swaps.
Compatibility with Ko Propo and Sanwa servo splines means installation is straightforward. Ensure the arm is centred on the servo spline before tightening to keep steering trims accurate.
