The ReadyLIFT 7" Complete Lift Kit System is specifically designed for 2015-2020 Ford F-150 4WD trucks offering maximum lift while maintaining factory ride and steering geometry. This premium kit includes a 7.0" front and 5.0" rear lift for rugged off-road strength and on-road comfort. It features precision-designed subframe assemblies that bolt in directly with minimal welding required. The kit includes heavy-duty cast nodular iron steering knuckles a patent-pending rack-and-pinion steering drop correction system and an integrated differential drop bracket system to ensure proper CV axle angles and 4WD performance. One notable feature is the patent-pending fabricated offset steel strut extensions providing a maximum 7" front lift while OEM-style rear blocks (total rear lift of 4.0" when installed) maintain ride quality. The kit also includes a steering extension to preserve steering performance eliminating the need to cut or replace tie rod ends. This no-weld design ensures easy bolt-on installation. Furthermore the kit incorporates a patent-pending Rack Correction System (RCS) to work with the relocated steering rack maintaining stock steering geometry. This prevents issues down the road as cutting tie rods can lead to alignment problems when replacing tie rods with OE replacements. The dropped rack and pinion system allows the truck to retain OEM alignment specs a stock turning radius and the stock track width. It even uses factory-style cam plates and can be aligned to factory specifications. The ReadyLIFT 7" Complete Lift Kit System is compatible with stock wheels or most 17" or larger aftermarket wheels with a wheel width of up to 9" and a backspacing of 4.75" - 5.5".
