The DJM brand kits are very nice. They make a 2/3 kit(2" front, 3" rear) and a 4/5 kit. I suggest the 4/5 kit. But......you need like a 26" tire or smaller to run the DJM 4/5. So unless your running 35 series tires, I'd do a 2/3.
DJM 2/3 kit consists of: Lowering Coils, Rear flip kit(roughly $400)
DJM 4/5 kit consists of: Lowering Coils, Upper and Lower control arms, Rear Flip Kit(Roughly $700)
Self install is pretty simple. Piece of cake if your mechanically inclined. My brother and I pulled it out overnight(6hrs?) takin' our time.
Here's my brother's '01 XL w/ the DJM 4/5 and 17" stang wheels(that push bar is long gone)....
