it is a 99 silverado reg cab step side... the rear leaf spring was just mounted below the axle with lowering shackles. It also has a 2 ch air ride kit on it. The front was almost completely redone with Bell Tech parts. I talked to a guy at 4wheel parts and he told me that I was going to need NEW lower control arms, NEW springs, NEW spindles, and NEW sway bar end links. I think I can handle doing the rear on my own with out having to buy too much stuff. But the front is a different story.
