I used the Suspension Maxx Jr. keys in mine and have been very happy with the kit. It included shock extensions for the front, new bumpstops, and a diff drop. Installed some Warrior shackles in the rear, but it still sits a little low due to the additional lift after I cranked the new keys an inch or so. This setup clears 33's on the stock wheels right now, and I'm probably into the whole kit about 550 bucks, not counting shipping and an alignement. I also installed longer shocks in the rear, as the stockers became too short with the shackle lift. They are KYB's, but I don't remember the part number. Truck rides alot better now.
