Application: Designed for 1994-2002 Mustang GT and 1999-2002 Mustang Cobras. Edelbrock Subframe
Connectors have been designed to add strength to the vehicle by connecting the front subframe from the front
suspension cradle mounting points to the rear suspension trailing arm mounts. The Edelbrock subframe
connector has large welding area to resist flex, heavy wall 1 5/8 diameter tubing for stability, and is contoured
to the floor pan of the vehicle so as not to reduce ground clearance.

MIG welder. The installer should have an understanding of welding dissimilar metals. The subframe

2. Subframe connectors should not be installed on a vehicle with subframe damage due to accident or
vehicles that have weak, unequal rate, or improper springs.
3. Due to high production tolerances and wear from age, some vehicles may require fitting of the
subframe connectors. This may require reshaping of the vehicles floor pan or subframe, or minor
grinding of the subframe connectors.
