Product Description

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 

Revshift polyurethane transmission mounts are made in the U.S.A. from high grade polyurethane.

Revshift mounts are the most durable and reliable mounts on the market. High tensile strength flanged studs are embedded deep in the urethane which prevent the isolated ends from separating under extreme loads. Utilizing class 12.9 alloy steel fasteners these mounts will hold your engine in place for a lifetime. The class 12.9 fasteners are approximately 75 percent stronger than the fasteners used on stock automotive mounts.



Please specify the hardness.

80A (BLACK) Stiff - Performance Street Applications

95A (GREEN) Hard - Aggressive street / Track Applications

75D (ORANGE)  Solid - Race Applications

What is Polyurethane?

 

Polyurethanes are a group of organic polymers that are normally grouped with rubber. Polyurethanes are elastomers which are stretchy materials. They come from the reaction of diisocyanates, long chain polyols and short chain extenders. This process has proven itself to be a flexible method of producing customised elastomers with adjustable properties.

Polyurethanes achieve hardnesses on a wider range than any other elastomer and exhibit outstanding physical properties such as: abrasion, by far better than steel; tear resistance, superior to these of many other elastomers; resilience; load bearing capabilities. Through the years, their special properties made them indispensable in more and more fields replacing other materials with lower properties.

- Our polyurethane can be tuned to produce polymers of different hardnesses and physical properties to suit the application

- Our polyurethane is elastic and can absorb an enormous amount of trauma without permanently deforming (unlike UHMW and Delrin)

- Our polyurethane is resistant to water, oil, gasoline, salt, antifreeze, and most solvents (unlike rubber)

- Our polyurethane is half the weight of aluminum and about 20% lighter than rubber
