Maximize Engine Stability with UMI Solid Mounts

For performance enthusiasts seeking ultimate responsiveness and control, the UMI Performance P/N 0059 Solid Engine Mount Kit is the ideal upgrade for your GM G-Body and F-Body vehicles. This kit is designed to place your Small Block Chevy engine in the exact factory location, utilizing UMI's popular P/N 0051 solid lower mount paired with a precisely laser-cut block mount. Engineered for high-horsepower applications, these mounts ensure your engine stays put, no matter the demands of the road or track.

Engineered for Performance and Precision

Constructed with tough 3/16-inch laser-cut brackets and Grade 8 hardware, these solid engine mounts are built to withstand extreme forces. By eliminating the flex associated with stock rubber mounts, they significantly improve throttle response and prevent unwanted engine movement. This is particularly beneficial in tight engine bays where large headers, turbochargers, or other components require precise engine placement. While solid mounts offer superior performance, it's important to note they are best suited for racing applications and may increase Noise, Vibration, and Harshness (NVH) within the cabin.

Key Features & Benefits:

  • Direct replacement for 1978-1988 GM G-Body and F-Body vehicles.
  • Maintains exact factory engine location for Small Block Chevy.
  • Durable 3/16" laser-cut steel brackets.
  • Includes high-strength Grade 8 hardware.
  • Enhances throttle response and drivetrain stability.
  • Prevents engine movement, crucial for tight packaging.
  • Ideal for racing and high-performance street applications.
  • Available in a sleek gloss black powder coat finish.

These engine mounts are proudly used on UMI's own G-Body test car, the "Green Machine" 1979 Monte Carlo. Experience the difference in performance and control with UMI Performance's USA-made solid engine mounts.
