The Meritor 7X121 key is a genuine Meritor part from Pro Gear and Transmission. A key is a small locating piece that seats in a keyway to hold two mating parts in position, so a worn, damaged or missing one is worth replacing before the parts can shift. Keys differ from one assembly to the next, and the right one depends on the exact axle and the position it goes into. Call us with your axle model and where the key sits, and we will help you confirm proper fit before you order.
