Steering Control Upgrade for Ko Propo and Sanwa Servos

The 3RACING 2.6mm Aluminium Single Servo Arm is a simple metal upgrade to sharpen steering feedback on your RC car. Finished in silver, it is built for hobby use where durability and repeatable input are important.

Why Metal Over Plastic

Aluminium offers reduced flex and better impact resistance compared with plastic. The 3RACING 3RAC-HKS26/SI keeps steering geometry more stable under load, which helps lap consistency at club tracks and practice sessions.

Where It Works Best

Specifically matched to Ko Propo and Sanwa servos, this arm is commonly used on touring and on-road machines where precise servo motion translates directly into cornering accuracy.

Will this improve cornering consistency?

Yes, increased stiffness from the aluminium arm reduces unwanted deflection, helping to keep steering inputs consistent from lap to lap.

Is any modification required for fit?

No modifications are generally needed for Ko Propo and Sanwa servos that share the standard spline. Fit with the correct mounting screw and confirm alignment.

Can I reuse my original servo mounting hardware?

In most cases yes. Keep the original screws if they match the arm's counterbore and length, otherwise replace with suitable hardware to avoid over-tightening.
