3.5" 2011-2016 Ford F250/F350 Super Duty 4wd (w/2 piece drive shaft) SST Lift Kit by ReadyLift

The ReadyLift 69-2531 SST Lift Kit is engineered specifically for 2011–2016 Ford Super Duty F-250, and F-350 4WD diesel trucks equipped with a two-piece driveshaft. This system provides the ideal combination of lift, performance, and ride quality while maintaining factory drivability.

Offering up to 3.5" of front lift and 1.5"–3" of rear lift, this kit delivers a level stance with clearance for up to 35"–37" tires, depending on wheel and tire configuration. Designed as a mild lift solution, it retains the smooth OEM ride while improving ground clearance and overall capability.

This comprehensive kit includes heavy-duty powder-coated steel coil spring spacers, radius arm drop brackets, and a track bar relocation bracket to properly correct suspension geometry at the new ride height. Additional components such as sway bar spacers, bump stop extensions, and shock extensions ensure proper suspension function and travel throughout the full range of motion.

In the rear, the system utilizes OEM-style cast lift blocks and extended U-bolts to provide the necessary lift while maintaining load capacity and durability. A carrier bearing spacer is included to correct driveline angles on trucks equipped with a two-piece driveshaft.

Built for durability and ease of installation, this SST system is a complete, bolt-on solution for Super Duty owners looking to enhance both appearance and performance without sacrificing ride quality.
