Performance focused 3RACING 3RAC-HKD30/SI aluminium servo arm

Engineered for competitive setups, the 3RACING 3.0 mm Aluminium Double Servo Arm delivers a firmer mechanical connection for Ko Propo and Sanwa servo outputs. The silver finish is functional and unobtrusive for race builds.

Material and stiffness advantages

The aluminium construction provides consistent behaviour under dynamic loads, and the 3.0 mm thickness minimises deflection at the control interface. This reduces variable steering inputs and aids repeatability during tuning sessions.

Application and setup notes

Suitable for on-road and off-road race cars where precise control is required. Ensure correct spline alignment and centring during installation to maintain optimal throw and endpoint symmetry.

What is the expected improvement in control response?

Switching from plastic to 3.0 mm aluminium reduces flex in the control linkage, producing more direct response and sharper repeatability under braking and cornering loads.

Any servo load considerations for tuning?

Aluminium arms transfer more torque to steering linkages; ensure your servo and linkages are rated for the applied loads and adjust endpoints to avoid binding at full throw.

Recommended installation practice?

Fit the arm with the correct servo screw, centre the servo before tightening, and verify free movement through the full travel. Use a small amount of thread locker on metal-to-metal fasteners in high vibration applications.
