Track-focused 3RACING 3RAC-HKS30F/RE servo arm

The 3RACING 3.0mm Aluminium Single Servo Arm is a lightweight yet stiff option for Ko Propo and Sanwa systems. The red anodized surface and true machining give a predictable feel under braking and cornering loads.

Where this arm fits best

Made for Ko Propo and Sanwa servo interfaces, this arm suits both competition cars and durable club rigs. It replaces softer plastic horns with a firmer connection to steering and throttle linkages.

Quick install and setup steps

Installation is simple due to accurate machining. Centre the servo before tightening the horn screw and check linkage alignment to preserve smooth travel. The 3.0mm thickness is a common choice for balanced performance.

Do I need new screws to fit this arm?

Most kits include the correct horn screw, but verify thread size and length. Using the correct screw prevents damage to the servo output shaft.

Will using this arm change servo speed?

The arm itself does not alter servo electronics. Slightly higher mass at the horn can affect responsivity minimally, but the 3.0mm aluminium is still light enough for most setups.

Can I reuse my existing linkages?

Yes, as long as the linkage holes and ball ends match the horn. Check that clevises or ball cups do not bind at full steering throw.
