I would run drop spindles in front, with or without drop springs. Drop spindles come in 2.5" and 3" depending on mfr. If you run 3" units, you will have to do some slight trimming on your LCA to clear the rims..UNLESS you have larger than 15" rims or rims with less BS than stock. You don't need to worry about any of this with 2.5" spindles.

For the rear, you can run a flip kit (5-6" depending on what rear leafs you have) without having to notch (but you might bottom out at times), or you can also install a shackle/hanger combo that will give you a 4" drop.

If you just want a mild drop, I would do spindles and shackles/hangers giving you about a 3/4 drop.
