UMI Performance 90058

The P/N 0058 heavy duty engine mounts for GM G-Body cars takes the place of the heavy factory clamshell mount. It places the Small Block Chevy in exact factory location and uses our popular P/N 90051 solid motor mounts or can be used with the factory rubber mounts. Tough 3/16” laser cut brackets and Grade 8 hardware can handle as much horsepower as you can throw at them. When used with P/N 90051, 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.
