The ICON Vehicle Dynamics 4.5-inch Front Diesel Dual Rate Spring Kit is specifically engineered for the 2023-2025 Ford F-250 and F-350 Super Duty 4WD. These springs are precision-tuned to accommodate the revised chassis and front-end weight of the 6.7L Power Stroke Diesel engine on the newest Super Duty platform. By utilizing a dual-rate design, ICON provides a significant performance upgrade over factory linear springs, delivering a plush ride on the pavement without sacrificing the stability and bottoming resistance required for heavy towing or aggressive off-road use.

Features
  • Diesel Optimized: Specifically tuned for the heavy front-end weight of 2023-2025 diesel models to ensure accurate lift height and optimal spring frequency.
  • 4.5-Inch Lift Height: Provides a commanding stance and the necessary clearance to fit 37-inch tires for increased ground clearance and off-road capability.
  • Dual Rate Design: Features a softer initial rate for superior small-bump compliance and a firmer secondary rate that engages during compression for better handling and bottoming control.
  • Increased Wheel Travel: Designed to work in conjunction with ICON shocks to provide up to a 50% increase in front wheel travel over the factory suspension.
  • Shot-Peened & Pre-Set: Manufactured to the highest standards to increase tensile strength and prevent sagging, backed by a lifetime guarantee.
  • Premium Finish: Finished in a dual-stage semi-gloss black powder coat for maximum protection against corrosion and road debris.
Notes
  • Specifically designed for 2023-2025 Ford F-250 and F-350 Super Duty 4WD models equipped with the Diesel engine.
  • Tremor-equipped models will see approximately 3.5 inches of lift over their factory height.
  • Requires the use of ICON or other aftermarket radius arms or radius arm drop brackets to maintain proper front-end caster and geometry.
  • An adjustable track bar or track bar drop bracket is mandatory to ensure the front axle remains centered at this lift height.
  • Requires recalibration of Advanced Driver Assistance Systems (ADAS) after installation.

I recommend them
Color: Black/Deep Blue/Red/Deep Grey, Size: Small
I bought it for my 11-year-old son who is 5'4" tall and weighs 124 pounds, and they fit him perfectly. It doesn't roll up and it has good elasticity
