Race-focused steering component

The 3Racing 3.0 mm Aluminium Double Servo Arm is aimed at drivers tuning steering response on Ko Propo and Sanwa systems. Its slim aluminium profile reduces rotational inertia while providing a firmer mechanical connection for sharper feedback at the wheel.

Technical highlights for setup and tuning

  • Material: Aluminium offers a high stiffness-to-mass ratio for minimal flex under load.
  • Compatibility: Produced to interface with Ko Propo and Sanwa splines for predictable geometry and repeatable setup changes.
  • Color: Anodised red finish allows quick visual checks when parc ferme or during setup changes.

Performance notes for racers

Using aluminium reduces arm deformation during high steering loads, helping maintain consistent toe and Ackermann responses. When tuning, confirm servo torque is adequate for the leverage applied by the double arm configuration.

Can I tune steering geometry with this arm?

Yes. The arm provides a stable mounting point for precise linkage adjustment, aiding in setting steering throw and centre points for competitive setups.

Should I worry about servo load with a double arm?

A double arm changes mechanical advantage; ensure the servo has appropriate torque to handle increased leverage to avoid overheating or reduced lifespan.

Any setup tips for track days?

Check spline engagement, use thread locker where appropriate on screws, and record changes so you can iterate steering geometry between sessions effectively.
