BMW Motor Mounts, Poly 75D – E39 (540, M5)

Part#: MM39VD

Product Description

Our BMW E39 (540, M5) Polyurethane (75D) Motor Mounts eliminate virtually all engine movement for effective power transfer through the drivetrain. Designed for racing, these bolt-through polyurethane motor mounts are engineered to be the strongest and most reliable on the market. Our exclusive design is stronger than the OEM mount, incorporates the correct height and mounting angle, consists of multiple parts and is fully rebuildable. The stock rubber engine mounts deflect as torque moves through the drivetrain, allowing the motor to move. Eliminate virtually all of this movement with our bolt-through BMW E39 (540, M5) poly 75D engine mounts.

These extremely hard, race-spec 75D durometer polyurethane motor mounts are the hardest available (aside from solid aluminum). They are the best option for race classes where solid mounts are not allowed, or for those who do not wish to deal with the issues that may arise when using solid mounts. The material used for the trans mount location(s) must match the material used for the engine mounts. 

Our U.S. Military Spec 75D durometer compound is as hard as a bowling ball, yet has elasticity and memory. This exclusive compound allows us to manufacture a mount that has virtually the same performance as a solid mount, but without the harshness on the brackets/chassis associated with solid mounts. Likewise, its elasticity and memory means they are also free from deformation which plastic mounts (Delrin, UHMW) are very prone to. Remember: proper heat-shielding is required on the exhaust side motor mount.

Made of our exclusive U.S. Military Spec polyurethane (75D hardness) and CNC’d 6061-T6 hard-anodized aluminum. Engineered for a perfect fit. Set of two fully rebuildable, bolt-through design motor mounts. Hardware Included. Read why our polyurethane mounts are the highest quality mounts available.
