    The UMI Performance solid engine mount kit replaces the soft factory rubber engine mounts with solid steel mounts to lock a small block Chevy engine firmly in place on 1978 to 1988 GM G-body cars. Removing the factory rubber keeps the engine from shifting under hard acceleration, which improves throttle response and drivetrain consistency. The kit bolts into the factory locations, is built from steel and finished in black powder coat. It is sold as a kit. UMI Performance manufactures this engine mount kit in the USA.

    FAQ

    What vehicles does this engine mount kit fit?

    It fits 1978 to 1988 GM G-body cars. See the vehicle applications list above and match your year, make and model.

    What do solid engine mounts do?

    Solid steel mounts replace the soft factory rubber mounts and hold the engine firmly in place, which reduces engine movement under hard acceleration and improves throttle response and drivetrain consistency.

    How does the kit install?

    The mounts bolt into the factory engine mount locations, so no modification is required for a standard fit.

    Is this kit made in the USA?

    Yes. UMI Performance manufactures this engine mount kit in the USA.
