UMI's solid motor mounts replace the factory rubber motor mounts to decrease engine movement for maximum vehicle performance. The frame-side solid mounts bolt directly to the frame of the 1974-1992 Camaro and Firebird and the 1978-1988 GM G-Body, as well as many other 1974 and up GM V8 applications. Solid mounts are required to be used with the factory block mount clamshells or UMI part number 90058 clamshells. The centerline is 1 inch from the cross member surface to the center of the hole, so check original parts dimensions before ordering. These solid mounts may not work with the Oldsmobile V8 style clamshell. UMI crafts these motor mounts in Philipsburg, PA, USA.
