Meritor A3211Z6682 is a genuine Meritor air brake spider assembly. In an S-cam drum brake the spider is the stationary mounting base at the wheel end: the brake shoes, their anchor pins and the camshaft head all locate on it, so the shoes and cam stay in the right relationship each time the chamber pushrod turns the cam. This spider has a 7.25 in. bolt circle diameter and a 5.50 in. pilot diameter, so check both against your axle before ordering. A genuine Meritor part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
