NOTE: Single Rear Wheel Trucks ONLY -- Not compatible with Dual Rear Wheels
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.
NOTE: 2020+ MY Super Duty may sit slightly taller in the rear than prior model years due block height variations from the Ford factory. The additional rake works well visually with the vehicle's body lines.
NOTE: Not compatible with TREMOR editions.
