3RACING 3RAC-HKS30/RE Race-Oriented Servo Arm

The 3RACING 3RAC-HKS30/RE 3.0mm aluminium single servo arm is tailored for tuners seeking repeatable steering response in practice and race conditions. Machined geometry and a protective red anodise make it a dependable element in a race setup using Ko Propo or Sanwa servos.

Consistent Response Under Load

The 3.0mm section reduces torsional deflection to maintain predictable toe and steering behaviour during aggressive driving. Use it where precise servo feedback is required for setup tuning and lap-to-lap consistency.

Installation and Setup Considerations

Install with the correct spline count and original servo hardware to preserve centring and travel. After fitting, verify end point and sub trim settings to integrate the arm into your tuned steering geometry.

After installation check servo centring, sub trim and travel limits to ensure the arm does not contact suspension parts at full lock. Fine tune end points for consistent steering sweep.
Yes. Confirm the servo spline count matches the arm to avoid play or binding. This arm is intended for Ko Propo and Sanwa servo patterns that align with its mounting layout.
By reducing flex it delivers more direct input, which helps drivers sense the traction limit sooner. Pair with appropriate steering rate and differential settings for optimal handling.
