Meritor A3211B7152 is a genuine air brake spider assembly. The spider is the foundation of a drum brake: the mounting base that carries the brake shoes, camshaft, rollers and related hardware, and it keeps the shoes in alignment so braking stays stable and consistent under heavy loads, heat and vibration. It has an 8.25 in. bolt circle diameter and a 6.75 in. pilot diameter, so compare both against your old spider before you order. A genuine Meritor part from Pro Gear and Transmission. Call us to confirm proper fit for your axle.
