Rear lift is achieved with our heavy-duty fabricated steel 6" tall rear lift blocks featuring OEM-style bump stop landings. We team the blocks up with a pair of double add-a-leaf springs to get a matching rear height to compliment the front lift. Included with this kit is a new transmission cross member and drive shaft spacer to optimize overall drive train geometry and provide smooth performance under acceleration. 49-2781 is for use on trucks with a two-piece drive shaft. Can allow for 37-38 inch tall tires. Diesel Engines Only. NOTE: The lift blocks in this kit are not designed to work with aftermarket or factory add-on air spring/load leveling kits that attach to the bump stop tangs. Use of this type of air bag system will void all block warranties and can cause failure of the block bump stop tang.
