Overview of the 3Racing 3RAC-HKS26/BU Servo Arm

The 3Racing 2.6mm Aluminium Single Servo Arm, built for KO Propo and Sanwa systems, is a practical upgrade to replace flexible plastic horns. The anodized blue finish and aluminium body provide reliable performance for everyday club running and practice sessions.

What It Brings to Your Setup

By cutting out play between the servo and linkage, this arm improves steering accuracy and repeatability lap after lap. Its construction suits a range of RC rigs from 1/10 street cars to 1/8 buggies used off-road.

Simple Installation and Fit Notes

Install using standard screws and tools; the 2.6mm bore ensures firm seating on compatible servo splines. Confirm your servo head dimensions and tighten to recommended torque to avoid slippage during aggressive driving.

Can I use this arm on a small crawler or micro vehicle?

It is designed for servos with a 2.6mm spline and standard mounting; micro crawlers usually use smaller splines, so check dimensions before fitting.

Will the metal arm cause more wear on the servo output?

A metal arm transmits forces more directly; ensure your servo has metal gears or adequate torque capacity to avoid premature wear on low-spec plastic gearboxes.

Do I need extra washers or spacers?

Some setups benefit from thin spacers to prevent binding or to set ideal steering throw; fit and test steering range before final assembly.
