UMI Performance 78-88 GM G-Body Solid Engine Mount Kit

The P/N 0059 solid engine mount kit for GM G and F-Body cars places the Small Block Chevy in exact factory location and uses our popular P/N 0051 solid lower mount combined with a laser cut block mount. Tough 3/16” laser cut brackets and Grade 8 hardware can handle as much horsepower as you can throw at them. Solid engine mounts improve responsiveness and help prevent engine movement, which can help in tight packaging situations (large header primaries, turbos, etc). Solid engine mounts work best in racing applications and may contribute to increased Noise, Vibration and Harshness. Available in gloss black powder coat. These engine mounts are proudly used on UMI’s G-Body test car, 1979 Monte Carlo “Green Machine”. 100% manufactured, tested and raced out of Philipsburg, PA – USA. Note: Heavy duty engine mounts may not work with Oldsmobile or Pontiac engines.
