ReadyLIFT Suspension 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 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 2011-2016 Ford Super Duty trucks with a diesel engines and a two-piece drive shaft. Does not fit the 2011-2016 Super Duty with the 6.2 liter GASOLINE engine. The 69-2531 3.5"F/3.0"R 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!

NOTE: This kit is for use on trucks with a two-piece drive shaft. If you have a one-piece drive shaft, use kit 69-2538.
NOTE: The lift blocks in this kit are not designed to work with aftermarket or factory add-on air spring/load leveling kits that attach to the bump stop tangs. Use of this type of air bag system will void all block warranties and can cause failure of the block bump stop tang.
Diesel engines only. Gas engine trucks will sit nose high.

NOTE: Tow Package vehicles may require longer U-bolts or removal of top overload springs.

Tire Fitment

37" Maximum tire diameter
37x12.50 for no rub on a 9" wide wheel with 0 offset
18" - 37X12.5R18
20" - 37X12.5R20
22" - 325/60R22
Tire Size Note: ReadyLIFT wheel and tire fitment recommendations are typically based on Wheel Pros wheels and Nitto tires. Due to product differences among tire manufacturers, tire specifications and dimensions including, but limited to, overall diameter, rolling diameter, tread width, aspect ratio, lug pattern, sidewall construction and inflation pressure, will vary meaningfully by tire and wheel manufacturer. Every tire and wheel combination should be test fit prior to installation. Consult your local installer to learn more about the right tire fitment for your application.
Ride Quality Note: When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer's construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 10-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.
