UMI Performance 74-92 GM F-Body GM G-Body Frame Side Solid Engine Mounts

UMI’s solid motor mounts replace the factory rubber motor mounts decreasing engine movement for maximal vehicle performance. Solid mounts bolt directly to the frame of the 1974-1992 Camaro/Firebird and 1978-1988 GM G-Body as well as many other 1974 and up GM V8 applications.. Solid mounts are required to be used in conjunction with factory block mount clamshells or UMI’s P/N 90058 clamshells. Note: Centerline is 1" from cross member surface to center of hole. Check your original parts dimensions before ordering. Solid mounts may not work with Oldsmobile V8 style clamshell. Crafted with pride in Philipsburg, PA- USA.

UMI Performance 90051 solid engine mounts are designed to replace factory rubber motor mounts and reduce unwanted engine movement for improved drivetrain control and vehicle performance. These frame-side mounts bolt directly into compatible GM applications, including 1974-1992 Chevrolet Camaro and Pontiac Firebird models, 1978-1988 GM G-Body vehicles, and many other 1974-and-newer GM V8 applications. They are a practical upgrade for performance-focused street, drag, and competition vehicles requiring increased engine stability.
The UMI Performance 90051 mounts must be used with factory block-mount clamshells or UMI Performance P/N 90058 clamshells. Before ordering, compare the original mount dimensions and mounting configuration to confirm compatibility. The mount centerline is positioned 1 inch from the crossmember surface to the center of the mounting hole. These solid mounts may not be compatible with Oldsmobile V8-style clamshells, so verify the engine and clamshell design before installation.
Built with pride in Philipsburg, Pennsylvania, UMI Performance 90051 engine mounts deliver a durable, direct-fit solution for reducing engine movement in select GM chassis. Their solid construction helps maintain consistent engine positioning under acceleration and shifting loads, making them well suited for vehicles where precise drivetrain control is a priority. Professional installation is recommended, and all related components should be inspected before use.
