Description

The UMI Performance 90059 is a solid engine mount kit designed for GM G-body cars. Constructed from tough 3/16” laser-cut steel brackets and featuring Grade 8 hardware, this kit is built to handle high horsepower applications.

Solid engine mounts enhance throttle response and minimize engine movement, offering benefits in tight engine bays with large headers or turbos. However, they are best suited for racing applications and may increase Noise, Vibration, and Harshness (NVH). The mounts are finished in a gloss black powder coat and manufactured in the USA.
