ReadyLIFT Smart Suspension Technology is used to make this kit very user-friendly to install, requiring no cutting or drilling.

Popular wheel and tire sizes used for this vehicle include the stock rims (17x8, 6.5" backspacing) with 37x12.5 tires, 20x9.5 rims (+25" backspacing) with 37x12.5 tires, and 22x9.5 rims (+25 backspacing) with 37x12.5.

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.
