The ReadyLIFT 4-inch Coil Spring Suspension System is a new Super Duty lift kit offering that includes Tubular Radius Arms, a Falcon Dual Steering Stabilizer, and new Falcon 3.3 piggyback shocks. This system provides Super Duty owners with an excellent alternative for lifting their trucks to fit larger tires and delivers a head-turning stance with improved ground clearance. This 4-inch lift height is often considered the 'sweet spot' for Super Duty driving dynamics, maximizing tire size while maintaining everyday usefulness. The combination of specially engineered coil springs, Falcon 3.3 shocks, and a track bar relocation bracket makes this a performance and ride-enhancing kit.

Features
  • Provides a 4-inch Coil Spring Lift Kit.
  • Includes vehicle-specific performance-tuned Falcon Shocks.
  • Features Tubular Radius Arms designed to correct the caster angle.
  • Includes a Falcon Dual Steering Stabilizer for superior truck stability, which reduces bump steer and improves steering feed.
  • The radius arms are formed inward, allowing for additional tire clearance.
  • Is a direct bolt-on lift kit with no structural modifications required.
  • Includes Falcon 3.3 monotube piggyback dampers on all four corners.
  • The Falcon 3.3 dampers offer a wide range of adjustability with 3-Position Fast Adjust Knob (Soft, Custom, Firm) and an 8-Position Micro Adjust Dial for refined damping.
Notes
  • Towing capacity will remain the same as factory.

  • The kit is intended for factory suspension and does not require upgrading leaf springs.

Very nice, much bigger than I thought it would be. Like the fact there are no stones to fall out so it will last for years to come. . It is of nice weight and very shiny and packaged very nicely. Super fast shipping. I switched out the chain with I had intended to do anyway didn't care much for the one that came with it it was shorter but expected for the price point.. but for $10 the charm itself was worth it. Very happy with purchase.
