Summit 2" shackles, and bell tech 2" spring mounts. Bell tech 2" upper shock relocator extenders, and will be buying lower shock relocator/extenders. Reason for that and drop spindles is i can use stock length shocks, and the extenders also relocate the shocks to a more upright position. I kept stock rear springs and installed polyurethane bushings. Reason for this is i use it as a truck, and wanted to keep it able to tow and haul stuff. Not sure how much useful load you get with de arched rear leaf springs If yours is a long bed, you will end up modifying stuff to fit. See my posts w pix in the lowering stupid questions thread. Lots of good detailed tips to help you even if your modding a shortbox truck. Bell tech is nicely made stuff, but not plug n play, i found myself grinding shit to fit and enlarging holes. Check out my posts there. I am happy w the results, however i also had all the tools at my disposal to giterdun without having to run and buy extra tools to do the job. I am a mechanic/fabricator by trade, so to me it wasnt a big deal, and i had what i needed to mod everything to work, plus i have been cutting on and modifying vehicles prob last 30 years or more. Easiest way by far to do this if your going to do front spring hangers is pull the bed off. Or at least lift it at the feont leaving the 2 rear bolts loosely installed. This gives you room to drill off the rivets, and get a wrench on the new bolts from the top. Change your fuel pump while your at it, easier to get to with the bed off. And if cutting with anything making sparks, cover up your back window with paper masking tape, masking paper or something of that nature to protect the glass from hot sparks embedding metal into the glass.
