If you're looking for a serious lift from your truck that is from a top quality manufacturer and want a problem free, weld free installation, this is a great kit for you! This COMPLETE lift kit comes with everything you need to lift your new F-150 up by a full 7" in the front. A precision designed laser cut CNC formed sub frame assembly means no welding is required. This is a bolt on kit! Ready Lift then uses a patent pending steering extension design, known as the Rack Correction System. The steering rack is relocated to maintain stock steering geometry. This is a safer and more reliable design than many other kits that require cutting or replacing the tie rod ends. This kit maintains stock track width and steering geometry, as well as turning radius, making this kit safer than many competing kits as well. Nodular iron lift spindles and smart strut extenders lift the front of the truck the right way. Differential drops with tortion bracing are also included to keep the differential from twisting and the axles in proper alighment. The rear is lifted with laser cut fabricated lift blocks and new U-bolts, as well as longer performance shocks. You can use your factory wheels with this lift kit, or you can use up to a 35 x 12.50 wheel with no rubbing. If you're okay with doing some minor trimming, you can run up to a 37 x 12.5 wheel with the proper offset. The part number for this item is Ready Lift 44-2575-K and it fits 2015-2018 Ford F-150 4WD models, lifting the truck 7" in the front and 4" in the rear.
