Solid bolt through 70D polyurethane motor mounts. Recommended for race use only. These mounts are designed for a 1983-1991 E30 BMW 3-series with an M20 engine. Revshift motor mounts are made by Revshift in the U.S.A. from high-quality 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 their original shape when deformed. 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.

Is your air conditioning system faulting by turning on and off at random, leaving you sweating in the hot summer days? The pressure switch shuts off the A/C compressor if the refrigerant pressure is too low or too high to protect your A/C system components from damage. If the switch is faulty, the A/C compressor will shut off at random intervals, or not turn on at all, without cooling the interior cabin. If this is the case with your A/C system, replace your pressure switch to restore cool air.

These are the stock rubber motor mounts for the E30 M20 engine - 325e and 325i. These are the original spec full rubber mounts. The M20 has a fatal flaw especially when the motor mounts are worn. The engine can shift and contact other things in the engine compartment, mostly cooling-related parts. This is especially troublesome on the 1984-1987 models as the alternator belt and blades can cut into the lower radiator hose. Don't neglect your motor mounts! A worn motor mount allows the engine to twist and shift around. The harder you're driving the more shift will occur. Twisting of the engine can also lead to shifting problems as the transmission twists with it. There are countless issues related to worn or compressed motor mounts so don't overlook these as a regular replacement item (every 50,000 miles).

For more serious track or street cars we recommend our HD motor mount kit with reinforcing cups - click here. These are a stiffer mount to begin with (coming from the Euro 635CSi) and the aluminum cups give additional strength especially for the side-side shearing loads that you get from cornering.

These stock rubber motor mounts are sold per mount .

This item fits the following BMWs:
1984-1991 E30 BMW 325e 325es 325i 325ic 325is

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 is the sealing o-ring used for many oil cooler kits on various BMW models. They're also a prime source for oil leaks because the o-ring gets 'flat' or shrinks or becomes damaged. These are usually easy to change though which puts an end to annoying small oil leaks.

These mounts are designed for an E30 with a M42 engine and an E34 with a M50 or M20 engine. 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.
