ReadyLIFT leveling kits are the fastest safest least expensive way to bring the front of an F-150 level with the rear. Our innovative Smart Suspension Technology mounts on top of the strut assembly eliminating the hassle time and danger of compressing springs. ReadyLIFT steel strut extension will maintain a smooth OEM ride without adding pressure to stock suspension components guaranteed! The 66-2059 strut extension provides 2" of lift which gives clearance to add up to 33" wheels and tires onto 2004-2014 2WD F-150 trucks and 35" tires on 2004-2014 4WD F-150 trucks. Installation is simple and requires no strut preloading cutting or modification of factory installed parts. While other kits cost thousands to buy and hours to install ReadyLIFT can be installed on a few hours and costs less than the price of a single custom wheel. All ReadyLIFT products are backed by a lifetime warranty for as long as you own your vehicle and includes all necessary parts hardware and detailed installation instructions.
