Yokomo B-MAX2 Precision 25T Servo Arm by Arrowmax AM-MAX2-011  [AM-MAX2-011]

High-strength 25-tooth servo arm

The Arrowmax AM-MAX2-011 replaces the factory plastic arm with a durable 7075-T6 aluminium unit, finished in blue anodize for corrosion resistance and a neat workshop look. It is produced to engage the standard 25-tooth spline used on Yokomo B-MAX2 servos.

Installation requires removing the stock horn, centring the servo, seating the AM-MAX2-011 onto the spline fully and refitting the original retaining screw. The profile of the arm is machined to follow the B-MAX2 steering geometry so it installs cleanly without extra modification.

In practice the alloy arm reduces play and resists deformation under repetitive steering loads, helping the car hold predictable steering inputs through corners. After fitting, verify steering centre and adjust end-points or trim if necessary to restore original travel and neutral position.
