Meritor AxleTech 1229R4204 is a genuine back up ring, sold by Pro Gear and Transmission. A back up ring is a stiff ring that supports a rubber seal so it keeps its shape and stays where it belongs. It is used alongside an O-ring so the softer seal is not squeezed into the clearance gap when pressure builds. This one comes from the AxleTech Genuine line of off highway hardware and is packed as one ring. Call us to confirm proper fit for your application.
