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

25T 7075-T6 servo horn

The Arrowmax AM-MAX2-011 is a blue-anodized 7075-T6 aluminium replacement made specifically to fit the Yokomo B-MAX2 chassis. As a direct 25T horn substitute for the stock plastic arm, it gives a firmer connection between the servo spline and steering linkage while keeping the standard 25-tooth engagement.

Fitting is simple: remove the original plastic arm, centre the servo, slide the AM-MAX2-011 fully onto the spline, and secure it with the factory retaining screw. The arm geometry is shaped to match B-MAX2 steering arcs so no trimming is normally required.

On track the 7075 alloy reduces flex under repeated inputs and preserves steering feedback through high-load transitions. Expect crisper steering return and improved repeatability versus a fatigued plastic horn; check end-points and trim after installation to dial the centre and travel back to spec.
