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.
Tools Required:
1. Common hand tools
2. Drive-on lift (preferred) or floor jack & stands
3. Soft-backed angle grinder / sander
4. C-clamps or Vice grips
5. MIG welder
Notes:
1. Weld-on subframe connectors should be installed by a professional welder with a proper wire feed or
MIG welder. The installer should have an understanding of welding dissimilar metals. The subframe
is formed from thin gauge sheet metal. The bracket of the Edelbrock subframe connectors are made
form 1/8 thick hot rolled steel that has been laser cut and formed to the required shape allowing for
minimum of gap.
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.
