Reliable steering upgrade with 3RACING 3RAC-HKS30/BU

This 3RACING 3RAC-HKS30/BU 3.0mm aluminium single servo arm is designed to provide a firmer steering feel for Ko Propo and Sanwa equipped cars. The aluminium construction aims to combine durability with low mass to help keep handling consistent.

Why choose a 3.0mm aluminium arm

A 3.0mm gauge balances stiffness and weight, reducing unwanted flex under load while avoiding excess heft. This helps maintain predictable steering behaviour in a range of driving conditions.

Installation and fit

The arm is compatible with common Ko Propo and Sanwa servo splines and installs with standard horn screws. It is a useful upgrade for anyone looking to refine steering precision without major setup changes.

Will this arm work on vintage servos?

It will work on many older Ko Propo and Sanwa models that share the same spline pattern, but confirm spline count and mounting hole alignment before purchasing.

Should I lubricate the servo spline?

Generally lubrication is not required on the spline itself. Keep screws snug but not over tightened and inspect periodically for wear.

Can I bend this arm to adjust geometry?

Aluminium is not designed to be bent repeatedly. If you need a different geometry, choose a suitable arm length or position rather than attempting to reshape this aluminium piece.
