Upgrade your linkage with the 3RACING 3RAC-HKS30/PU servo arm

The 3RACING 3.0mm Aluminum Single Servo Arm in purple is a straightforward upgrade for Ko Propo and Sanwa servos, giving a clean, low-mass connection that suits both track and backyard use. Its compact profile helps maintain precise servo response without adding unnecessary weight.

Built for precise control

Made from quality aluminium, this 3.0mm arm balances strength and lightness to improve steering feel and reduce flex. The accurate thickness and machining ensure a predictable link between your servo and steering or throttle linkages, so tuning stays consistent lap after lap.

Where to use it

Designed primarily for Ko Propo and Sanwa compatible splines, this arm fits a variety of touring cars and 1/10 scale models. It suits on-road setups as well as milder off-road use where a stable, metal arm is preferred over stock plastic parts.

Will this arm fit servos from other makers?

This arm is made to match Ko Propo and Sanwa spline patterns. Some other servos use the same spline, but fit is not guaranteed without checking spline type and screw hole alignment.

Is aluminium better than plastic for steering arms?

Aluminium offers cleaner feel and greater wear resistance compared to stock plastic arms. It cuts down on flex for sharper steering but can transfer more shock to the servo, so check mount protection for heavy impacts.

Do I need special screws or washers to fit it?

Most installations use the same screw pattern as stock arms. Small shims or thin washers can help fine tune throw and centre, but no special hardware is normally required for Ko Propo or Sanwa servos.
