Find Parts That Fit Your Vehicle

Drivetrain Mounts and Upgrades

From the factory, engine and transmission mounts are rubber and thus a wear component. Worn out engine or transmission mounts create sloppiness and a disconnect between the driver and your BMW's powerplant. If your vehicle is purpose built for the track, we recommend solid engine and transmission mounts. These have zero deflection, but come at the expense of added NVH (noise, vibration, and harshness). Poly engine and transmission mounts offer a good balance between OEM rubber and solid mounts for those with mixed purpose vehicles, offering great performance and connection with little sacrifice in terms of NVH.

These mounts are designed for the BMW E36 and E46 including the M3, Z3, and Z4 as well as the E90/E92 M3. Excluding the E46 XI. 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 prevents 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. These mounts have removable screws for ease of installation. We recommend using Loctite on the threads during installation. Revshift Performance Engineering is a high-performance parts manufacturer with a focus on quality, reliability, and performance. Utilizing high-precision machining technologies and their very own Polyurethane Manufacturing Department, every Revshift product is designed, manufactured, and tested in-house at their Detroit, Michigan facility.

These specific mounts are designed for those with clearance issues on extremely low E30s. They are 20mm taller than OEM mounts to add necessary clearance to ensure the oil pan sits above the stock subframe. Under hard braking the OEM rubber mounts allow the m20 to lean forward. Not only do these solid UHMW replacement mounts stiffen the engine and drivetrain, but they also raise the engine by 20mm, dramatically changing the responsiveness and raising the oil pan height of your E30. UHMW is an excellent general-purpose plastic with a unique combination of wear and corrosion resistance, low friction surface and impact strength. It is resistant to chemical attack and moisture absorption and retains key physical properties to -30 C. This kit includes Solid Transmission Mounts as well for fully solid powertrain mounting!

Solid bolt through 70D polyurethane trans mounts. Recommended for race use only. These trans mounts fit almost all BMW cars excluding the E30 M3 and a few older models. They commonly fit the E30, E36, E46, E9x, E8x, E21, E34, E39. Common BMW part numbers that these trans mounts replace are: 22316799331 23711175939 23711175424 23701141614 Revshift polyurethane transmission mounts are made in the U.S.A. from high-grade polyurethane. 70D polyurethane has a comparable hardness to plastics such as Delrin and UHMW. Unlike plastic, polyurethane is an elastomer which means it will return to its original shape if deformed and it will not crack. We do not recommend plastics for automotive use due to their inherent brittleness and inability to return to its original shape when deformed.
