ICON 2023 Ford F-250/F-350 Super Duty 4–5.5″ Stage 4 Coilover Conversion Kit

Swapping aging torsion bars for monotube gas-charged coilovers restores steering precision, prevents front-end squat under cargo, and adds measurable off-pavement clearance.

• Cylinders are machined from 6061-T6 aluminum alloy with anodized wear rings and Grade 8 steel mounting brackets designed to absorb repeated impact loads without fatigue deformation.
• Delivers a controlled 4–5.5 inch front lift that accommodates up to 35-inch tires while preserving optimal caster and thrust angles for stable highway cruising.
• Dual expansion packs enable independent rear preload adjustment, allowing owners to dial out levitator-style bounce and maintain truck-level posture when hauling trailers or decked beds.
• Direct bolt-on geometry utilizes existing frame rail holes and differential subframe points, eliminating the compromised alignment and increased bearing stress caused by stock spring spacers.
• Fits exclusively 2023 Ford F-250 and F-350 Crew Cab 4WD gasoline pickups; verified clearance avoids inner fender contact and works within the manufacturer's recommended wheel backspacing parameters.
• Replaceable internal piston seals and nitrogen-precharged reservoirs extend shock service life well beyond factory rubber isolators that crack, leak fluid, or lose valving consistency.

Initial setup requires torquing castle nuts to specification and greasing the supplied zerks before lowering the vehicle onto wheels, but all necessary hardware, preload shims, and step-by-step orientation labels secure a complete OE-footprint installation.
