Simple performance upgrade: 3RACING 3RAC-HKS30/PU

The 3RACING purple 3.0mm Aluminium Single Servo Arm offers a no-fuss replacement for Ko Propo and Sanwa servos, improving linkage stiffness and feel. It is a practical part for anyone refreshing a car or refining steering response.

Reliable construction

Aluminium construction gives this arm solid wear resistance and predictable mechanical behaviour. At 3.0mm thick it keeps flex to a minimum while remaining light enough to maintain crisp servo action during frequent steering inputs.

Where it works best

Made to suit Ko Propo and Sanwa mounting patterns, this arm suits a wide variety of 1/10 scale on-road cars and light off-road models. It provides consistent operation across different driving surfaces and tuning tweaks.

Does this arm need a specific servo horn size?

This arm uses the common Ko Propo and Sanwa spline dimensions. Confirm your servo spline matches those patterns before purchasing for a direct fit.

Can I bend it back after a crash?

Aluminium can sometimes be reshaped, but repeated bending weakens the metal. Replacement is usually safer and keeps predictable control geometry.

Is there a performance gain over stock parts?

Aluminium arms reduce flex compared to many stock plastic parts, which can sharpen steering response. The benefit depends on the rest of your setup and how you tune servo endpoints.
