Race-Oriented Steering Component

The 3RACING 3.0mm Aluminium Double Servo Arm is focused on precise steering control and setup flexibility. Made for Ko Propo and Sanwa systems, it supports detailed trim and endpoint adjustments prized in race tuning.

Performance-Focused Construction

Constructed from aluminium for consistent stiffness under load, the double arm configuration helps maintain predictable torque transfer during hard cornering and quick transitions.

Tuning and Fitment Notes

The purple finish is cosmetic, while the 3.0mm thickness is chosen to balance rigidity and weight for competitive setups. Confirm mounting and linkage geometry when integrating into a tuned chassis.

How does this arm affect steering response?

The aluminium arm reduces flex compared with stock plastic horns, tightening steering feel and improving consistency lap after lap when used with matched servos.

Any setup tips for competition?

After fitting, adjust endpoints and subtrim to restore neutral steering. Test small changes to arm length or link position to dial in turn-in and mid-corner behaviour.

Is aluminium recommended for racing classes?

Aluminium arms are common in competitive builds for their repeatable performance. Ensure the additional stiffness suits your chassis tuning to avoid unwanted handling shifts.
