Rattlebox, I have the Skjacker 4. 5" Double-Flex system in my truck. The kit comes complete with new front springs, adjustable front trailing arms with beefy heim joints, track bar relocation bracket, double shock mount (front only), single steering stabilizer, new bumpstops, and brackets to relocate the stock brake lines. The rear suspension consists of new rear leaf springs and shocks. I would spend the extra money and get the Nitro shocks. My truck rides way better than stock, and is extremely stable in turns. The only bad thing that I can say about it is the red powdercoating on the front suspension got ugly real fast, as well as the paint on the rear leaf springs. The shock tubes are getting a little rusty. My next project will be detailing the suspension with some Rustoleum. Other than that it is a well engineered suspension. I don't think you'll be disappointed. One word of advise concerning tires. Stay away from Interco TSL Super Swamper radials. See my post in the products section. Regards, -Glen Pratt
