Control upgrade for 3RACING 3RAC-HKS30/LB owners

The 3RACING 3.0mm Aluminium Single Servo Arm designed for Ko Propo and Sanwa systems replaces weaker plastic arms with a more durable aluminium option. The light blue anodised finish keeps the look tidy while resisting everyday wear.

Intended applications

Perfect for racers and hobbyists who want a firmer steering input, this arm helps maintain alignment under load and reduces unwanted flex during aggressive driving or repeated use.

Compatibility tips and quick fitting

Made to suit common Ko Propo and Sanwa servo splines, the arm is a straightforward swap. Centre the servo and confirm link lengths after fitting to ensure accurate steering geometry.

Is this suitable for competitive use?

Yes, its aluminium construction offers greater stiffness than stock plastic parts, making it a sensible upgrade for club-level competition where repeatable steering is important.

Will it work with my current link rods?

Most link rods that fit Ko Propo or Sanwa arms will work, though you should verify hole spacing and adjust rod ends if necessary for correct geometry.

How do I care for the aluminium surface?

Keep the arm free of grit and clean with mild soap and water after dusty runs. Avoid abrasive cleaners to preserve the anodised colour and finish.
