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.
