Upgrade Steering Accuracy

The 3RACING 3.0mm Aluminium Single Servo Arm is a compact, reliable part that tightens steering response for RC cars and trucks. Made for direct fit with Ko Propo and Sanwa systems, it installs quickly and keeps control feel consistent.

Durable Aluminium Build

Manufactured from machine-grade aluminium, this arm balances low weight with good strength to resist wear during regular club use. Its rigid profile helps reduce slop in the steering linkage for crisper inputs.

Engineered for Ko Propo and Sanwa Fitment

Precision hole spacing and a standard spline interface let this arm mate cleanly with Ko Propo and Sanwa servos, maintaining predictable steering geometry whether you are tuning for speed or stability.

Will this arm work with older Ko Propo or Sanwa servos?

It is designed to match the common spline patterns used by Ko Propo and Sanwa, so it will fit most legacy and current servo models that use the standard interface.

Is aluminium better than plastic for this part?

Aluminium provides greater resistance to wear and flex than typical plastic arms, which helps keep steering precise during repeated use.

Any tips for installing the servo arm?

Centre the servo, fit the arm to the correct neutral spline, and tighten the securing screw to the servo maker's recommended torque to avoid stripping or binding.
