  • ReadyLIFT® Suspension Inc. has engineered a line of suspension products made to fit the 2011-2016 Ford Super Duty equipped with diesel engines. Our 2011-2016 F250 4WD 3.5"F/1.5"-3.0"R SST Lift Kit is our Super Duty lift kit and provides the exact amount of front and rear lift while allowing for wheel and tire combinations up to 35" and keeping the smooth OEM ride and drivability. This ReadyLIFT SST Lift Kit is the perfect Lift Solution for the 2011-UP Ford Super Duty trucks with a diesel engines and a two-piece drive shaft. Does not fit the new 2011-UP Super Duty with the 6.2 liter gas engine. The 69-2531 3.5"F/3.0"R Stage 4 SST Lift Kit includes 3.5" powdercoated steel coil spring spacers, sound isolators, shock extensions, sway bar frame mount spacers, bump stop extensions, carrier bearing spacer, track bar relocation bracket, radius arm drop brackets and OEM-style 5.0" Rear Lift Blocks for a great looking mild lift system that will maintain your factory ride!

    This kit is for use on trucks with a two-piece drive shaft. If you have a one-piece drive shaft, use kit 69-2533.

    When it comes to lifting your 2011-UP Ford F250 F350 or F450 Super Duty, the ReadyLIFT 69-2531 SST Lift Kit system gives you everything you need to raise your Super Duty 3.5" in front and 3.0" in the rear or 1.5" in the rear depending on what block you have. This great new system made to fit the 2011-2016 Ford F250 F350 F450 4WD specifically incorporates more than just front leveling or a simple lift. Our popular 3.5" coil spacers and sound isolators retains 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. Radius arm drop brackets and a new track bar relocation bracket keeps the suspension geometry in tact. In addition, Ford changed the front suspension on the 2011-2016 Super Duty 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 won't get with other kits. Our bumpstop extensions allows you to retain the factory distance between the bump stop and axle while a provided carrier bearing spacer gives you the opportunity to adjust your driveshaft angle as needed. The use of OEM-style cast iron 5.0" rear lift blocks (3.0" lift) in conjunction with the the 3.5" front lift will make the 2011-2016 Ford Super Duty sit with a mild lifted stance.

    ReadyLIFT's 3.5" SST Lift Kit for the 2011-UP Ford 4WD Super Duty trucks is a safe, easy way to lift 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® Smart Suspension Technology is used to make this kit very user friendly to install, requiring no cutting or drilling. Professional installation time is estimated at 5 hours.
