Solid bolt through 70D polyurethane motor and trans 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 its original shape when deformed.Lifetime warranty
