Performance-Focused 3RACING 3RAC-HKD26/SI Servo Arm

The 3Racing 2.6mm Aluminium Double Servo Arm is intended for tuners and racers using KO Propo or Sanwa servos who need a dependable metal horn. Its straightforward aluminium profile provides consistent actuation with minimal added mass.

Servo Compatibility and Setup

Manufactured to engage KO Propo and Sanwa spline patterns, the arm ensures a firm interface between servo output and linkage. Use it to replace trimmed plastic horns or to refine steering geometry for sharper response.

Material Choice and Track Benefits

Aluminium delivers a balance of stiffness and lightness that reduces flex at the servo output, translating to improved control fidelity during aggressive inputs and repeatable lap-to-lap performance.
