I bought a four bar setup from CPP and it turned out to be a Total Cost Involved unit. The quality was good and the installation was very easy. The coil over springs that came in the kit are a bit stiff, unless you have a work truck, but that's an easy fix. The real beauty of a coil over setup is the ability to taylor height and ride quality at a very low cost, springs are cheap. If you are building a hot rod type of truck go for it, if you plan on a bed full of rocks and 100,000 miles stay with leaf springs.
