You really need to do your homework based on your particulars and the end result you are looking for. If you are keeping the same wheels and tires, will they fit with 2" spindles still? Is a 2" drop what you are looking for? Do you want to go lower? Will the wheel contact the lower control arm if you go that route and keep your wheels? Do you need spacers or different wheels? How many leaves do you have? Are the suspension components in good shape? Springs not fatigued, bushings good? My suggestions is to measure everything, check everything, create a list of parts you will need and action items. summitracing is a good source but there are many others out there too. Sounds like you will need, lowering spindles, shackles, shocks, boots, & maybe wheel spacers, to begin with. Once you start changing to lowering springs and removing leaves the ride quality will be altered.
