Sharper steering with the 3RACING 3RAC-HKS30/BU arm

The 3RACING 3RAC-HKS30/BU 3.0mm aluminium single servo arm is aimed at hobbyists seeking firmer steering feedback on Ko Propo and Sanwa servos. The aluminium build provides a strong, lightweight option for improving steering feel.

Design focused on control

The 3.0mm section minimises flex while keeping weight low, helping to preserve handling balance. This makes the arm a sensible upgrade for drivers who want more direct steering without compromising speed.

Compatibility notes

Made to work with common Ko Propo and Sanwa splines, the arm is easy to fit and serves as a practical replacement part to fine tune steering geometry and response.

Is this suitable for competitive use?

Yes, the 3.0mm aluminium construction of the 3RACING 3RAC-HKS30/BU helps reduce flex, which can be beneficial in competitive settings where consistent steering is important.

Does the blue finish affect fitment?

The finish is cosmetic and does not change spline fit or hole spacing. Fitment depends on matching the servo spline type and mounting position.

How should I check neutral after fitting?

Set the servo to neutral with your transmitter, install the arm on the neutral spline, then adjust link lengths so the steering arms sit square for accurate centring.
