3RACING 2.6mm Aluminium Double Servo Arm for Ko Propo/Sanwa - 3RAC-HKD26/BU  [3RAC-HKD26/BU]

Race-Oriented 3RACING 3RAC-HKD26/BU Aluminium Servo Arm

The 3RACING 2.6mm Aluminium Double Servo Arm is developed for competitive tuning where steering precision matters. Manufactured to interface with Ko Propo and Sanwa splines, the alloy construction reduces compliance and improves repeatable control inputs for tighter lap times.

Performance Advantages for Tuners

Compared with polymer horns, aluminium maintains geometry under high torque and repeated loads. The double-arm configuration increases lateral stiffness and ensures consistent toe and steering centre during setup changes.

Installation and Setup Considerations

Fitment to Ko Propo and Sanwa servos is direct; check spline type and secure mounting hardware to avoid play. The 2.6mm thickness is selected to offer a balance between minimal flex and acceptable weight for racing applications.

Finish and Durability

The anodised blue finish resists wear and helps protect mating surfaces from contaminants. For race use, inspect after impacts and replace if deformation is detected to maintain precise steering calibration.
