Sharper Steering for Hobby Builds

The 3RACING 3.0mm Aluminium Single Servo Arm is a no-nonsense upgrade that sharpens steering control on both road and off-road models. It is engineered for Ko Propo and Sanwa compatibility and fits with standard servo hardware.

Quality Aluminium for Consistent Use

This arm uses durable aluminium to resist deformation under load, helping it retain alignment and reduce steering play after many runs. The lightweight design keeps unsprung mass low where relevant.

Direct Fit to Ko Propo and Sanwa Splines

Accurate hole placement and spline matching give a clean fit to Ko Propo and Sanwa servos, maintaining reliable steering geometry for lap time or casual driving sessions.

Is this suitable for electric touring cars?

Yes, it suits touring cars that use Ko Propo or Sanwa servos and where riders want firmer steering feedback.

How do I pick the right arm length or position?

Choose the arm position based on the servo spline and desired throw; shorter lever reduces throw but increases steering force, longer includes more movement.

Can I polish or anodise this arm?

Surface finishing is possible but may require professional anodising to maintain tolerances; consult a workshop for best results.
