Hey man! Sorry it took so long to get back to you! I bought the McGaughy's 2/4.5 drop. (spindles, and flip kit for the back. I removed the overload spring, installed the flip kit, then put the stock shackles back on for a good 6 inches of drop. Installed the drop spindles in the front, but had to notch them to fit with the beefy 4x4 lower control arms. Not really that hard, just had to use a drill press and grinder. Also loosened the torsion bars just a little for an extra 1.5 inches of drop. The installed some McGaughy's air bags on the rear frame rails. Aired them up to about 15-20 psi, until the truck was perfectly level. I have a video on you tube of a walthrough, with the bed removed. Prolly help out alot!
