Yokomo B-Max2 23T Servo Arm 7075 by Arrowmax AM-MAX2-009  [AM-MAX2-009]

High-precision 23T servo arm

This servo arm is a 23T replacement horn manufactured by Arrowmax for use with the Yokomo B-Max2 chassis, finished in blue anodized 7075-T6 aluminium. It is intended as an RC-scale spare to replace the stock plastic arm and to provide a firmer mechanical link between the servo and steering linkage.

On the B-Max2, switching from a plastic horn to a 7075 aluminium arm reduces flex at the servo output, which helps translate servo movements into more repeatable steering input during tuning and track runs. The anodized surface resists wear from metal-to-metal contact and helps prevent corrosion in regular maintenance cycles.

Installation is straightforward: remove the original arm, confirm the servo spline is centered, fit the Arrowmax 23T arm onto the 23-tooth spline, and secure with the original mounting screw. After fitting, check horn alignment and steering travel before final runs, and recheck fasteners after the first few sessions.
