3RACING 3RAC-HKS26/PU 2.6mm Purple Aluminium Single Servo Arm for Ko Propo Sanwa  [3RAC-HKS26/PU]

Performance-Focused 3RACING Servo Arm

The 3RACING 3RAC-HKS26/PU 2.6mm aluminium single servo arm is produced to meet the needs of racers using Ko Propo and Sanwa servos. Its dimensional consistency supports repeatable geometry and predictable steering behaviour.

Application and Fitment Details

Engineered to interface with common Ko Propo and Sanwa spline standards, this arm provides a secure coupling and minimal play. It is suitable for both fine steering adjustments and aggressive track use where response repeatability is critical.

Material and Design Considerations

The 2.6mm aluminium profile delivers a high stiffness-to-weight ratio, reducing compliance at the horn while limiting added rotational inertia. This helps maintain servo bandwidth and improves steering precision under load.
