Improve Steering Precision

The 3RACING 3.0mm Aluminium Single Servo Arm is a compact upgrade aimed at reducing play in the steering linkages of RC cars. It is purpose built to work with Ko Propo and Sanwa servo systems and fits using standard mounting hardware.

Reliable Aluminium Construction

Crafted from aluminium, the arm is resilient to everyday wear and keeps its shape under load, helping to preserve steering consistency over time.

Made to Match Ko Propo and Sanwa Interfaces

Hole patterns and spline alignment are set to match common Ko Propo and Sanwa servos so the arm installs cleanly and keeps steering feel predictable for track or park sessions.

Will this work with my existing servo horn?

If your servo horn uses the standard spline pattern found on Ko Propo and Sanwa servos, this arm will fit directly; verify spline count before fitting.

How should I maintain the arm for long life?

Inspect mounting points regularly, clean grit from around the spline, and avoid over-tightening the fixing screw to prevent wear.

Is this a good upgrade for club racing?

Yes, it provides firmer steering feedback and reduced play, which helps drivers maintain consistent inputs during competitive running.
