ReadyLift has engineered a new line of suspension products made to fit the 2011 Ford Super Duty. The SST lift kit provides the exact amount of front lift to level the new F250 trucks while allowing for wheel and tire combinations up to 35 inch and keeping the smooth OEM ride and drivability. This ReadyLift stage 2 SST lift kit takes the stage 1 leveling kit a step further and includes the 2.5 inch powder coated steel coil spring spacers, sound isolators, shock extensions and sway bar frame mount spacers found in the stage 1 kit, but also includes ReadyLifts popular OEM-style cast iron 4.0 inch rear lift blocks. When it comes to lifting the 2011-UP Ford F250 Super Duty you get what you pay for. This great new system made to fit the 2011 Ford F250 4WD specifically incorporates more than just front leveling. The addition of the 4.0 inch rear block kit in the stage 2 kit allows the 2011-up F250 owner to establish a mild lift all the way around while maintaining a very slight rear rake. The popular 2.5 inch 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. In addition, Ford changed the front suspension on the new 2011 F250 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 wont get with other kits. If you are looking to make the 2011 F250 4WD sit level then this strong 2.5 inch leveling kit is exactly what you need.
