Meritor A3211N5474 is a brake spider assembly with a 7.25 in. bolt circle diameter and a 5.50 in. pilot diameter, the two measurements to match before you order.
A brake spider is the structural mounting hub of a drum brake. It carries the cam shaft, brake shoes and related hardware and takes the braking reaction load. Cracks around the mounting holes or the cam bushing seat, stretched holes and pitting on the thin arms are the usual signs a spider is finished, and a distorted one shows up as uneven shoe wear. A genuine Meritor part from Pro Gear and Transmission. Call us to confirm proper fit for your axle.
