get ready for the rear of the truck to settle and look funny make sure you get full rear spring and not add a leaf and block or you will have bad axlewrap and last but not least look into Kore engineering suspensions they are light years ahead on technology and off road capability and street performance is uncomparable to any other suspension setup on the market. If my advice doesnt work for you just order extra polyurethane bushings for control arms a set of 1" blocks for the rear and a new track bar setup for the stock ball joint is to weak for the lifted application
