The ReadyLIFT 4-inch Coil Spring Lift Kit is a new suspension system designed for the Power Stroke diesel trucks. This kit includes front and rear Falcon 1.1 Monotube performance shocks, providing a great ride and handling performance, and is designed to improve stance, performance, and capability. It is considered the 'sweet spot' for Super Duty driving dynamics and maximum tire size while maintaining everyday usefulness. The coil spring system allows for increased tire sizes and widths along with providing improved ground clearance. The coil springs are OEM style linear springs specific for the diesel spring rate.

Features
  • Provides a 4-inch front coil spring lift.
  • Includes four Monotube Falcon 1.1 Shocks.

  • Includes model-specific brake line extension brackets, bump-stop extension brackets, and front sway bar frame mount extension brackets.
Notes
  • Tremor versions will not gain the full 4 inches over stock ride height.
  • Trucks equipped with the "Onboard Scale" option will require the Auto-Leveling Headlight Bracket (PN 67-23410).
  • If installed on a gas truck, the vehicle will be nose high and have a stiff ride because the springs are designed and rated for the heavier diesel engine.

Cute but not hinged at arms
Color: Porcini Tortoise, Size: 52-17-140
They were cute. I didn’t like that they weren’t hinged. They were harder to open and close. I didn’t look for this feature before I purchased.

Mis lentes son muy cómodos, y me gustan como lucen, vienen sin medidas yo los adecué con mi Optometrista. Se aflojan con el tiempo, pero compré una pinza que ajusta los tornillos…realmente lucen como nuevos.
