I used the McGaughy's 2"/3" kit. It is springs only (includes new hardware) front and rear. I then sourced all the other parts wherever they could be found (PRG and others). I used a slightly shorter Bilstein strut in the front and stock lengths in the rear. I also replaced all the rubber bushings everywhere in the font end with Delrin or urethane pieces. Replaced all four ball joints with Moog Problem Solvers, Moog tie rod ends, PRG end links and more. The only thing in the entire front end that didn't get replaced was the steering rack although it did get urethane rack bushings.
Now, as far as the way the truck drives, it's very, very good! It handles very solid and doesn't wander at all and no longer changes ones when I hit a big bump! I run a 305/15/20 tire. The ride quality os bit of a different story. On a good quality highway, the ride os fine. You'll feel any imperfections in the road through the steering wheel but the ride is fine. On a bumpy road however, it'll turn you teeth into Chiclets! I still want the rear slightly lower which I'll likely accomplish with new shackles and Roadmaster Active Suspension setup will complete my upgraded suspension rebuild.
Overall, it's a blast to drive it and I'm not sorry I lowered it one bit despite the ride quality on bad roads. It's not my daily driver which may actually be part of the problem which I'll explain. Ride quality would be improved by using rubber bushings. They are much softer and more forgiving than urethane or especially the Delrin materials. My daily is a Mercedes-Benz S500 which is obviously an extremely smooth riding car so jumping in the truck after driving the Benz for a week or two may cause the ride issues to seem more extreme than they actually are.
Belltech has a couple of pretty comprehensive kits available for 2"/4" drop. They do a flip kit while the McGaughy's kit does not. You can but the kits with or without shocks. I have heard the shocks are poor quality so if you went that way my advice would buy the kit without the shocks and find a good quality shock like Bilstein or KYB.
