Details

The best just got better. ReadyLIFT the trusted leader in Super Duty suspension is proud to launch the next evolution in performance and ride quality: our premium 2.5" Leveling Suspension System (PN: 46-20254) built specifically for 2017-2026 Ford Super Duty diesel trucks.

At the heart of this system lies our precision-engineered Falcon 2.1 Series shocks, paired with heavy-duty coil springs and a full suite of supporting components to deliver unmatched on- and off-road performance. This isn't just a leveling kit it's a truck transformation.

Why this kit is a game-changer:

• Falcon 2.1 Monotube Shocks Precision-tuned for exceptional ride quality, control, and durability
• Run up to 35" tires (or 37" with minor trimming) for aggressive stance and capability
• Unmatched on-road ride quality meets trail-ready toughness
• Complete bolt-on system with sway bar, bump stop, and brake line extension brackets included
• Command the road with added clearance, comfort, and confidence

Whether you're towing heavy loads, commuting to the job site, or hitting backcountry trails, this new ReadyLIFT system delivers the rugged stance you want with the smooth ride you need.

Note: 2017-2019 Super Duty trucks will achieve a 2" front lift. Tremor versions will gain 1.125 inches over stock ride height.

Notes: For trucks with the Onboard Scale option, don't forget to pair it with our Auto-Leveling Headlight Bracket Kit (PN: 67-23210). Model year 2023-2026 Tremor models gain 1.125" of ride height. Some 2020-2026 Super Duty trucks retain use of the factory track bar bracket. If the front axle is shifted off center with the kit's trackbar bracket, use the original factory bracket.

Tire and wheel fitment

35x12.50 for no rub on a 9 or 10 wide +25 to 0 offset wheel

37 is possible but may require trimming.

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.
