The Meritor A3211X7252 is a genuine OEM air brake spider assembly designed for heavy-duty drum brake axle ends. The spider mounts to the axle flange with a 7.25 in. bolt circle diameter and accepts a 5.50 in. pilot diameter, two critical dimensions that determine fitment to your specific axle. Sourcing the correct brake spider matters: a mismatched pilot or bolt circle means the S-cam and brake shoes will not align properly. This is a genuine Meritor part sold by Pro Gear and Transmission. Call us to confirm proper fit for your axle application.
