The Meritor A3211Y6837 is a brake spider assembly engineered for the CQN419 cam brake model. The spider features an 8.25-inch bolt circle diameter and a 6.75-inch pilot diameter, two dimensions that are critical for correct mounting and alignment at the wheel end. Proper spider fitment keeps the S-cam brake foundation geometry in spec and ensures the brake shoes seat correctly against the drum. VMRS code 013-002-105 identifies this as a foundation brake spider component. Call us to confirm this spider is the right fit for your axle and brake configuration before ordering.
