Setup Focused Steering Component

The 3RACING 2.6mm Aluminium Single Servo Arm is intended for racers and tuners using Ko Propo and Sanwa servos who need predictable, repeatable steering inputs. Its aluminium profile reduces deflection under load compared to typical plastic horns.

Compatibility and Fit Considerations

Engineered to align with Ko Propo and Sanwa splines, this arm supports straightforward fitment and stable control response. Verify spline match and mounting hardware to ensure precise engagement and minimal slop.

Tuning and Durability Notes

As a robust alloy option, the arm holds up under typical track loads and allows fine adjustments using different mounting holes and radio end point settings. Regular inspection of the bore and screw torque will maintain consistent performance.

What should I check for precise installation?

Confirm spline compatibility, clean the servo output shaft, fit with correct screw type and torque, and verify centring before final tightening to avoid misalignment.

How does this arm affect tuning adjustments?

Reduced arm flex provides more predictable steering gains from endpoint and trim changes, making tuning of Ackerman and steering ratio adjustments more repeatable.

Is this arm suitable for incremental upgrades during a setup session?

Yes, its reliable fit and consistent stiffness make it useful when testing small setup changes, as it keeps mechanical variables stable while you tune electronics and suspension.
