1973 – 1991 C-20 / C-30 (8 LUG) 4″ Complete rear leaf spring hanger and shackle kit by djm
If you want a little more drop than a shackle gives just add the leaf spring hanger to the mix and you have a traditional Hanger/Shackle kit. Your moving each end of the leaf spring up 2″ on the frame for a total of 4″. Takes some “elbow grease” to get those rivets out of the factory hanger but darn well worth it!
