Sharper steering with the 3RACING 3RAC-HKS30F/BU horn

The 3RACING 3.0mm aluminium single servo arm is a tidy upgrade aimed at KO Propo and Sanwa users wanting firmer steering response. The blue anodized finish provides a durable surface and a neat appearance.

Reasons to fit an aluminium arm

Aluminium arms cut down on flex and deliver more accurate control inputs compared with plastic. That predictability aids both precision driving and repeatable setup work at the track.

Compatibility and common uses

Built for KO Propo and Sanwa servos, this arm suits a wide range of applications from precision on-road racing to general off-road use where stronger steering linkages are desired.

Installation and maintenance notes

Fit by matching the spline profile and securing with the correct fasteners. Check mounting tightness regularly, and inspect for any signs of wear after heavy sessions to keep performance consistent.

Is this compatible with high-torque servos?

Yes, the aluminium arm is suitable for high-torque servos, but confirm spline match and ensure the servo case has clearance for the arm movement.

Will the arm wear the servo spline faster?

A tighter fit transfers more load; check both arm and servo spline periodically. Proper seating and correct screw torque will minimise premature wear.

Can I use this with aftermarket steering linkages?

Yes, it works with common linkage setups. Verify hole positions and geometry to maintain correct steering ratio and avoid binding.

Does the colour affect performance?

No, the blue anodizing is cosmetic and protective. Performance is determined by the material and design rather than the colour.
