2005-2008 Ford Mustang Edelbrock Coupe Sub-Frame Connector

Designed to fit 2005-2008 Ford Mustang Coupe, Edelbrock sub-frame connectors are stronger and more effective due to (1) Large welded surface area, (2) connects rear suspension connection point to engine cradle and front K-member, (3) ground clearance is minimally affected.
Notes:
1. Weld-on sub-frame connectors should be installed by a professional welder with proper equipment and a good understanding of welding dissimilar metals. The sheet metal used to form the sub-frame of the vehicle is relatively thin. The end brackets of the Edelbrock sub-frame connectors are made from 1/8 thick hot-rolled, laser-cut and formed to fit the vehicle’s sub-frame.
2. Sub-frame connectors should not be installed on vehicles that have sub-frame damage due to accident or vehicles with weak or unequal rate springs.
Installation: Disconnect negative battery cable. Jack up and support vehicle, support vehicle with jackstands, rated to support vehicle weight on a level and solid ground. Jackstands must be set so vehicle’s weight is loaded as if vehicle were being supported by its wheels. A drive-on style lift or drive-on stands are preferred. Unbolt parking brake cable brackets from rear lower trailing arm sub-frame pocket. Remove under car wind deflectors. Remove nut retaining fuel lines just rear of left side wind deflector. Slide left side mid frame bracket #23-2156 above fuel lines, taking care when prying fuel lines down so not to bend or kink them. Bolt bracket to outer sill rail using two(2) supplied 10mm bolts washers and lock washer. There are nut inserts in sill rear. Unbolt only the left side rear engine - K-member bolts. While carefully prying down on K-member, slide left Edelbrock sub-frame connector #25-4085 between K-member and vehicle floor. Align front of Edelbrock sub-frame connector bolt holes with K-member bolt holes. Use supplied 10mm bolt washer and lock washer to bolt rear of sub-frame connector up to vehicle’s sub-frame. Mark around where Edelbrock sub-frame connector is to be welded to vehicle and mid sub-frame bracket. Remove Edelbrock sub-frame connector. Clean off paint and any under coating.
