The ICON Stage 1 Suspension System with Radius Arms is built for drivers who split their time between job sites, back roads, and towing duties. With 2.5 inches of lift, your truck gets the stance you’re after while keeping ride quality smooth and predictable on all terrain. ICON’s fabricated radius arms not only add serious strength but also improve tire clearance so you can fit up to 37-inch tires without rubbing. Whether you're hauling equipment or heading into the hills for a weekend getaway, the tuned dual rate coils and 2.0 Aluminum Series shocks give your truck a confident feel without compromising on control. Every part of this system is designed to bolt on without cutting or welding, making the install straightforward for most garages. Backed by ICON’s proven testing and engineering, this kit delivers a ride that’s as capable as it looks.\u003c\/p\u003e\n\u003ch4\u003eEvery Piece Works Together For Maximum Performance\u003c\/h4\u003e\n\u003cp\u003eThis Stage 1 system combines ICON’s dual rate coil springs and 2.0 Aluminum Series internal reservoir shocks to deliver improved wheel travel, better control, and a more planted feel compared to stock. The coil springs are tuned specifically for diesel trucks, offering the perfect balance between load handling and ride comfort. ICON’s fabricated radius arms feature on-vehicle caster adjustment and a sealed pivot bushing that reduces feedback while keeping operation quiet. The internal reservoir shocks are valved for this specific truck platform and are fully rebuildable and re-tunable for future upgrades. Even under heavy loads or rough roads, the geometry of the suspension remains stable and predictable thanks to the added rigidity from the radius arm design. The system maintains full towing capacity and requires no modifications to the driveshaft. With a fully bolt-on installation, this is a performance upgrade that delivers real improvements without added complexity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e 2023, 2024, 2025 Ford F250\/F350 Super Duty 4WD\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOnly fits 4WD models and is not compatible with F-350 Cab \u0026amp; Chassis configurations.\u003c\/li\u003e\n\u003cli\u003eCoil springs are specifically tuned for diesel engines only.\u003c\/li\u003e\n\u003cli\u003eTrucks with the Tremor package will see approximately 1.5\" of front lift instead of the full 2.5\".\u003c\/li\u003e\n\u003cli\u003eDoes not require driveshaft modifications for installation.\u003c\/li\u003e\n\u003cli\u003eInstallation is fully bolt-on with no cutting or welding needed.\u003c\/li\u003e\n\u003cli\u003eAn adjustable track bar may be needed to properly realign the axle.\u003c\/li\u003e\n\u003cli\u003eRecalibration of Advanced Driver Assistance Systems (ADAS) is required after install.\u003c\/li\u003e\n\u003cli\u003eMay require sensor bracket #66203 if equipped with OnBoard Scales.\u003c\/li\u003e\n\u003cli\u003eBrake line kit (#61111) is optional but recommended for cleaner routing or braided upgrade.\u003c\/li\u003e\n\u003cli\u003eICON track bar bracket (#64039) is recommended to correct bump steer geometry.\u003c\/li\u003e\n\u003cli\u003eCompatible rear shocks support 0-3\" of rear lift over stock.\u003c\/li\u003e\n\u003cli\u003eAllows clearance for 37\" tires but may require trimming or modification.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Icon Vehicle Dynamics","offers":[{"title":"Default Title","offer_id":53252606624028,"sku":"IVDK65890R","price":2913.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/K65890R_23-25_Ford_F250-F350_Stage1_web_large_24b5f35c-c845-4398-9fb3-79fc0fac6b62.jpg?v=1761764643","url":"https:\/\/www.alligatorperformance.com\/products\/icon-k65890r-2-5-3-lift-stage-1-coilover-conversion-system-with-radius-arms-2023-2025-ford-f250-f350-super-duty-4wd-copy","provider":"Alligator Performance","version":"1.0","type":"link"}
