Elevate towing stability and off-road capability with the ICON Stage 5 Coilover Conversion Kit for 11-16 Ford F250/F350, engineered with adjustable 2.5- to 3-inch ride height, dual-rate springs for impact protection, and comprehensive expansion hardware for complete suspension customization.

The ICON 11-16 Ford F250/F350 Stage 5 Coilover Conversion System replaces aging factory suspension components with monoleaf coils and dual-valve dampers to deliver precise handling across highway cruising and extreme trail conditions. This kit resolves the typical conflict between light-load comfort and heavy-payload support by integrating dual-rate spring technology, which engages a soft initial rate to absorb road vibrations before transitioning to a progressive second-stage rate that safeguards the frame during high-compression impacts. The mounted twin tubular reservoirs significantly increase oil volume and surface area, facilitating rapid heat dissipation that eliminates damping fade during repeated suspension cycling, rock crawling, or prolonged mountain hauls.

Constructed from billet aluminum reservoirs and equipped with titanium-coated sealing shafts, the dampers offer superior corrosion resistance and reduced internal friction compared to standard coated components. The kit includes full expansion pack accessory hardware, granting the flexibility to reposition spring coils between axles or adapt individual units to different chassis locations without requiring additional purchases. Installation remains a direct replacement operation that preserves proper track width, avoids fabrication errors, and restores accurate steering geometry when paired with a routine alignment.

• Adjustable Stance Control: Set ride height continuously within a smooth 2.5- to 3-inch lift range using precision-threaded spring adjusters and matched upper mounting hardware.
• Dual-Rate Spring Engineering: Coils feature a two-stage design that maintains a relaxed feel on pavement while locking out forcefully under severe load to prevent harsh bottom-outs and protect drivetrain integrity.
• Piggyback Heat Dissipation: Remote reservoirs maximize thermal management by expanding fluid capacity and exposure, ensuring consistent damping performance regardless of ambient temperature or usage intensity.
• Expansion Pack Versatility: Supplied adapters and shims enable custom suspension layouts, allowing users to swap front and rear coil applications to optimize weight distribution for oversized tires or specialized towing loads.
• Titanium-Sealed Longevity: Internal dampers utilize dual valve designs with titanium nitride shaft coatings to minimize seal wear, repel abrasive debris, and extend maintenance intervals beyond conventional steel systems.
• Direct Retrofit Compatibility: Manufactured specifically for 2011–2016 F-250 and F-350 chassis models; bolts securely to existing frame brackets and leaf eye hardware without cutting or modification.

Assembly durability and long-term reliability are guaranteed under ICON's limited lifetime warranty covering mechanical components, providing peace of ownership for commercial fleets and enthusiast operators alike.
