This new suspension design is still in use today on Fords very popular “Superduty” line, but it all started here with the 1965 F-100. This 3/4 kit uses our “Dream Beams” which give you a 3″ drop by simply removing the factory beam and replacing it with our new Dream Beam! The rear is lowered with a hanger / shackle kit that yields a full 4″ drop. Just moving the leaf spring up on the frame is how this works. You won’t believe the stance of your “effie” after you install this kit and neither will your friends!
