3RACING 3RAC-HKS30F/BU Blue 3.0mm Aluminium Single Servo Arm for KO Propo Sanwa  [3RAC-HKS30F/BU]

Stiffen your steering with the 3RACING 3RAC-HKS30F/BU

The 3RACING 3.0mm aluminium single servo arm is a no-fuss upgrade for KO Propo and Sanwa servo users. The blue anodized arm increases steering precision and stands up better to repeated use than plastic alternatives.

Aluminium advantages for everyday running

Aluminium reduces unwanted flex and gives a more direct feel through the steering linkage. That steadier input helps drivers maintain consistent lines and quicker reaction to corrections.

Vehicle fit and typical applications

Ideal for a broad range of RC models equipped with KO Propo or Sanwa servos, this arm works well on both street-style touring cars and performance off-road machines seeking crisper steering.

Installation pointers

Install by matching the spline and seating the arm squarely on the servo. Tighten fasteners to a secure setting and recheck after a few runs to ensure nothing has loosened.
