McGaughys incredibly strong and durable motor mounts are 100% made in the USA and have been designed to fit your 1955-1957 Chevrolet Fullsize Car. Our mounts are made out of superior-quality steel, which means they will have a very long life span and last you for many years to come! They even have a nice-looking black powder coat finish, which only adds to their aesthetic value and style. McGaughys mounts accommodate seamless or 2pc frames, and offer you the option to simply replace your stock motor mounts retaining the original engine location, or move the whole engine forward 3/4".
