ReadyLIFT Suspension Inc. has engineered a new line of suspension products made to fit the Ford Super Duty. Our Stage 1 2011-2012 F350 4WD 2.5 in. leveling kit provides the exact amount of front lift to level the new F350 trucks while allowing for wheel and tire combinations up to 35 in. and keeping the smooth OEM ride and drivability. This ReadyLIFT Leveling Kit includes 2.5 in. powdercoated steel coil spring spacers, sound isolators, shock extensions and sway bar frame mount spacers. When it comes to leveling you get what you pay for. This great new system made to fit the 2011-2012 Ford F350 specifically incorporates more than just front leveling. The sound isolator is installed between the spacer and spring to retain that great OEM ride and quiet sound. Shock extensions allow you to retain the use of those great riding brand new front shocks rather than having to replace them with cheap aftermarket versions. In addition, Ford changed the front suspension on the new 2011-2012 F350 trucks and in order to level the truck the front sway bar frame mounts must be spaced downward. ReadyLIFT designed new sway bar mount spacers just for this reason, something you will not get with other kits. If you are looking to make your 2011-2012 F350 4WD sit level then this strong 2.5in. Leveling kit is exactly what you need! ReadyLIFTs NEW 2.5 in. Stage 1 leveling kit is a safe, easy way to level your Super Duty while maintaining your factory ride. Why spend thousands of dollars for an elaborate mega-lift kit that takes extensive time to install while destroying your ride when you can save money and get a great lift height that rides great and looks awesome while achieving exactly what you wanted to do. ReadyLIFT SST is used to make this kit very user friendly to install, requiring no cutting or drilling. Professional installation time is estimated at 1-2 hours. Like all other ReadyLIFT kits, Stage 1 Leveling Kit is guaranteed for life against manufacturing defects.
