This 23T servo horn from Arrowmax is intended for the Yokomo B-Max2 chassis and is manufactured from 7075-T6 aluminium with a blue anodized finish. It replaces the original plastic arm to provide a firmer mechanical connection between the servo and steering linkages.
Converting the B-Max2 to a 7075 aluminium arm reduces flex at the servo output, improving the repeatability of steering inputs during setup and on the circuit. The anodized surface helps resist wear where metal parts contact and assists in corrosion prevention during routine servicing.
To fit, remove the original horn, centre the servo spline, press the Arrowmax AM-MAX2-009 onto the 23-tooth spline and fasten with the original mounting screw. Verify horn alignment and steering travel before running and recheck all fastenings after initial use.
