ReadyLIFT Suspension has engineered a 3.5" lift kit made to fit the 2017-2023 Ford F250/F350 SuperDuty 4WD trucks with a two-piece drive shaft. These new 3.5" lift kits allow for wheel and tire combinations up to 37" while keeping the smooth OEM ride and drivability. This is a complete lift kit includes 4" OEM-equivalent rear blocks with integrated bump stop landings, 3.5" coil spring extensions with sound isolators, an OEM-style panhard drop bracket, front bump stops OEM shock extension brackets, a pair of radius arm drop brackets, and all needed hardware. When used with the maximum size tires, the F250 truck body is raised over 6".
ReadyLIFT Smart Suspension Technology is used to make this kit very user-friendly to install, requiring no cutting or drilling. Like all other ReadyLIFT kits, the F250/F350 3.5" SST Lift Kit is guaranteed for life against manufacturing defects.


NOTE: For use with trucks with a two-piece drive shaft.

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.

NOTE: 2020-22 MY Super Duty may sit slightly taller in the rear than prior model years due block height variations from the Ford factory. The additional rake works well visually with the vehicle's body lines.

NOTE: Not compatible with TREMOR editions.

Recommended tire size: 37" - 12.5"

Recommended wheel: 17" and up x 9" wide, +25 offset / 6" backspacing (minor trimming of the front valance may be necessary)

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.

Please read Instructions thoroughly and completely before beginning installation. Installation by a certified mechanic is recommended.

Estimated Installation Time: 6 Hours +/- 1 hour (excluding alignment and wheel/tire assembly)
