Polyurethane Transmission Mount

Each mount is constructed with CNC machined billet aluminum flanged ends, ensuring they are embedded deep within the urethane to prevent separation under extreme loads. The use of Class 12.9 alloy steel hardware guarantees a lifetime of reliable performance. Revshift offers these transmission mounts in three distinct hardness levels to suit various driving needs: the 80A Street (Black) option provides a stiffer and stronger alternative to OEM rubber with minimal increase in noise, vibration, and harmonics (NVH), making it an excellent OEM+ upgrade. For enthusiasts who drive enthusiastically on the street and track, the 95A Track (Green) variant offers significantly stiffer and stronger performance with a noticeable increase in NVH. Dedicated drift and track cars can benefit from the 75D Drift (Teal) mounts, which are drastically stiffer and stronger, offering a moderate increase in NVH. These transmission mounts are designed to fit almost all BMW cars, commonly including models like the E30, E36, E46, E9x, E8x, F3x, F8x, E21, E34, and E39. They are a direct replacement for several BMW part numbers, including 22316799331, 22322282340, and 23711175939, among others. Please note that the E30 M3 and a few older BMW models are excluded from fitment. The product is sold as a pair and comes with a lifetime warranty.
