  • ReadyLIFT Suspension is pleased to announce A new Super Duty Suspension System.  We are now shipping our 4" Coil Spring Lift Kit, #63-27440, fitting 2017-2022 Ford Super Duty F250/F350 4WD Power Stroke® trucks. The new 4" lifts include front and rear Falcon 2.1 Falcon shocks. This kit is designed to improve stance, performance, and capability and includes everything necessary to clear larger wheels and tires. With vehicle-specific performance-tuned Falcon 2.1 dampers on all four corners, these lift kits provide a better-than-factory feel.  Falcon Performance Shocks improve performance and comfort regardless of the terrain. The versatility of these systems makes them ideal for daily driving, off-road excursions, and tow/haul duties. This gives Super Duty owners an excellent alternative for lifting their trucks to fit larger tires. The coil spring system allows for increased tire sizes and widths along with providing improved ground clearance on a head-turning stance!  Many consider this lift height the 'sweet spot' for Super Duty driving dynamics and maximum tire size while maintaining everyday usefulness.

     

    This optimum lift height allows for up to 37" tall tires. The coil spring kit delivers a great ride and handling performance! The key ingredients to improving Super Duty ride and handling are the new, specially engineered coil springs teamed with Falcon 2.1 shocks and a track bar relocation bracket! This combination is more than just a lift kit, this is a performance and ride-enhancing kit that will really delight consumers with how well it rides and performs both on and off-road.

    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.
