BMW HD Rubber Transmission Bushings (OEM+ upgrade)

BMW HEAVY-DUTY RUBBER TRANSMISSION BUSHINGS (OEM+ UPGRADE) Overview These HD Transmission bushings stiffen up your transmission mounts without adding noise into the cabin or sacrificing comfort. A great OEM upgrade to most manual transmission BMWs are these factor E21 transmission bushings because they are already stiffer then most other OEM BMW units. The OEM number is 23711175424. Please keep in mind because these are stronger than OEM replacements, the stud on these is M10 instead of M8, so the hole will need to be enlarged using "X" size drill bit. This is a great upgrade for the daily driver E30, E36, E46, E90 and more!
