Transmission Mount Set

The RevShift 80A Black Polyurethane Transmission Mounts (PTM-BT-80A) are engineered to provide a superior upgrade over stock rubber mounts for a wide range of BMW vehicles. With an 80A durometer rating, these mounts offer a "OEM+" feel – slightly stiffer and stronger than original equipment but without the significant increase in noise, vibration, or harshness (NVH) that harder compounds can introduce. Manufactured in the USA from premium polyurethane, the PTM-BT-80A mounts are designed for longevity and performance. They incorporate robust construction methods, including CNC-machined billet aluminum flanged ends that are deeply embedded to resist separation, even under high stress. The use of class 14.9 alloy steel screws, which are thread-formed for enhanced durability, ensures that these mounts will securely hold your transmission in place. The screws are also removable for easier installation. These transmission mounts replace common BMW part numbers such as 22316799331, 22322282340, 23711175939, and others. They are generally compatible with most BMW models, with the notable exclusion of the E30 M3 and a few older variants. Specific fitments include the E30, E36, E46, E9x, E8x, F3x, F8x, E21, E34, and E39 chassis. RevShift offers these transmission mounts as a pair and backs them with a lifetime warranty. Installation is straightforward, and the use of Loctite on the threads is recommended for optimal security. If you prefer a stiffer setup for aggressive street or track use, RevShift also offers 95A Green and 70D White compounds.
