Polyurethane Motor Mounts - BMW E34 / E39

These mounts are designed for the BMW E34 with an M30 or S38 engine and the BMW E39 with an M52 or M54 engine. Revshift polyurethane motor mounts are made in the U.S.A. from high grade polyurethane. Revshift mounts are the most durable and reliable mounts on the market. CNC machined billet aluminum flanged ends are embedded deep in the urethane which prevent the isolated ends from separating under extreme loads. Utilizing class 14.9 alloy steel removable screws these mounts will hold your engine in place for a lifetime. To further ensure the strength of these mounts we form the threads with a forming tap which creates denser and stronger threads in the billet aluminum end pieces.
