Description
The Meritor Brake Spider A3211Q3917 is a genuine Meritor OEM drum brake component designed to mount the S-cam brake assembly at the wheel end. This spider carries a 7.25 in. bolt circle diameter and a 5.75 in. pilot diameter, two dimensions that are critical to confirming proper fit before ordering. The VMRS code 013-002-105 classifies it within the foundation brake system.
