• ReadyLIFT Suspension is pleased to announce A new Super Duty lift kit.  We are now offering our first 4” Coil Spring Kit including Tubular Radius Arms and Falcon Dual Steering Stabilizer, #49-23421. The new 4” lifts include front and rear Falcon 1.1 Monotube series performance shocks with our venerable front track bar relocation bracket, tubular radius arms or radius drops, and rear fabricated blocks. 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.

  
  

  The all-new Radius Arms are designed to correct the suspension geometry on lifted models. These new radius arms are heavy duty and are built to handle the use and abuse demanded out of Super Duty trucks. The new radius arms hold up to the abuse and surpass the factory radius arms and support gussets. The arms are formed inward, allowing for additional tire clearance, and providing the ability to install oversized tires. The direct bolt-on design promotes quick and easy installation.
  

   

  
  

  With the help of Falcon steering dampers in the 49-23421, ReadyLIFT’s new Dual Steering Stabilizer provides superior truck stability which is crucial for any solid front axle vehicle equipped with oversized-sized tires. Falcon steering stabilizers allow for more confident handling over the road and in challenging terrain. They reduce bump steer and improve steering feed contributing to overall truck comfort and security thanks to the increased truck maneuverability and control.

   

  
  

  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 1.1 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 Fitment

  • 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.
