Finally, a 100% polyurethane engine mount available for a Mopar! The Chevy guys have had these for years, so we figured it was about time to bring our Mopars into modern day technology also. Polyurethane offers stiffness and strength far beyond the factory "rubber" mounts. It lasts much, much longer than rubber, it won't crack or dry out. And it will handle the power of a big displacement engine without the harshness and 100% vibration transfer of a solid steel mount. These are sold as a pair. They fit B bodies from 1966-72, C bodies from 1966-73 and E bodies from 1970-74.
