Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.\u003c\/p\u003e\n\n\u003ch2\u003eTunable Damping, Front and Rear\u003c\/h2\u003e\n\u003cp\u003eBoth the front remote reservoir and rear piggyback reservoir shocks carry ICON's CDC Valve, giving 10 externally accessible compression damping settings from soft to hard. That range means the same truck can run a compliant highway setting on a long tow and a firmer off-road setting on a trail without pulling a shock off the vehicle or reaching for a laptop. Because the shocks are fully rebuildable and re-tunable, the damping character can be updated as driving needs change rather than replaced outright.\u003c\/p\u003e\n\n\u003ch2\u003eRadius Arms Built for Clearance and Caster\u003c\/h2\u003e\n\u003cp\u003eThe fabricated, fully boxed radius arms include a sealed pivot bushing that reduces road noise transmission and is designed for long service life. The arm profile is optimized so a 37-inch tall tire clears the radius arm at full steering lock without contact. On-vehicle caster adjustment is built into the arm, so alignment can be dialed in without removing the system. The adjustable front track bar keeps the axle centered and improves handling geometry after the lift is installed.\u003c\/p\u003e\n\n\u003ch2\u003eNo Towing Capacity Change, No Driveshaft Work\u003c\/h2\u003e\n\u003cp\u003eThe Stage 4 system increases wheel travel and improves ride quality over stock while maintaining the truck's towing capacity. No driveshaft modifications are required. The dual-rate coil springs carry a lifetime guarantee against sagging or breaking and are rated specifically for gasoline-engine load characteristics.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCDC Valve shocks, front and rear:\u003c\/strong\u003e 10 compression damping settings adjustable on the vehicle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.5 Aluminum Series shocks:\u003c\/strong\u003e remote reservoir up front, piggyback reservoir in the rear, fully rebuildable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFabricated radius arms:\u003c\/strong\u003e fully boxed, sealed pivot bushing, on-vehicle caster adjustment, 37-inch tire clearance at steering lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual-rate coil springs:\u003c\/strong\u003e rated for gasoline engines, lifetime guarantee against sag or breakage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable front track bar:\u003c\/strong\u003e corrects axle placement and handling geometry post-lift\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100% bolt-on installation:\u003c\/strong\u003e no drilling, cutting, or welding required\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eDetail\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eVehicle Fitment\u003c\/td\u003e\n      \u003ctd\u003e2023–2026 Ford F-250 \/ F-350 Super Duty, 4WD, gasoline engine\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLift Height\u003c\/td\u003e\n      \u003ctd\u003e2.5 inches (based on 4WD Crew Cab gas; Tremor package yields 1.5 inches over stock)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Shocks\u003c\/td\u003e\n      \u003ctd\u003eICON 2.5 Aluminum Series CDCV, remote reservoir (part 67800CP, qty 1 pair)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Shocks\u003c\/td\u003e\n      \u003ctd\u003eICON 2.5 Aluminum Series CDCV, piggyback reservoir (part 37705CP, qty 1 pair)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDamping Adjustment\u003c\/td\u003e\n      \u003ctd\u003e10-position CDC Valve, front and rear, externally adjustable on vehicle\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCoil Springs\u003c\/td\u003e\n      \u003ctd\u003eDual-rate, gas-engine rated, 2.5-inch lift (part 62517, qty 1 kit)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRadius Arms\u003c\/td\u003e\n      \u003ctd\u003eFabricated, fully boxed, sealed pivot bushing, on-vehicle caster adjust (part 64043, qty 1 kit)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eTrack Bar\u003c\/td\u003e\n      \u003ctd\u003eAdjustable front track bar kit (part 64038, qty 1)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Shock Compatibility\u003c\/td\u003e\n      \u003ctd\u003eCompatible with 0–3 inches of rear lift over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOEM Wheel Fitment\u003c\/td\u003e\n      \u003ctd\u003eYes\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended Aftermarket Wheels\u003c\/td\u003e\n      \u003ctd\u003e17×8.5 with 5-inch backspace \/ 6 mm offset; 18×9 with 5.25-inch backspace \/ 6 mm offset; 20×9 with 5.25-inch backspace \/ 6 mm offset\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended Tires\u003c\/td\u003e\n      \u003ctd\u003e35×12.50 (37×12.50 may fit but requires fender trimming and modifications)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e220 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003eK65898R\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThis system suits 2023–2026 Ford F-250 and F-350 Super Duty trucks in 4WD configuration with gasoline engines, including those used for towing, job-site work, and off-road driving, where the owner wants externally tunable damping and improved tire clearance without modifying the driveshaft or losing towing capacity.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis system does not fit F-350 Cab and Chassis models, any 2WD Super Duty, or diesel-powered Super Duty trucks. Trucks equipped with the Tremor package will see 1.5 inches of front lift rather than 2.5 inches. Trucks with Ford's OnBoard Scales system require an additional sensor bracket (ICON part 66203, sold separately). Advanced Driver Assistance Systems (ADAS) require recalibration after installation. The bump steer geometry correction bracket (ICON part 64039) is separately recommended. The brake line kit (ICON part 61111) is optional and not required for a complete install.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eDoes this system fit diesel-powered F-250 and F-350 trucks?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eNo. The ICON Stage 4 system for 2023–2026 Ford F-250\/F-350 Super Duty uses dual-rate coil springs rated specifically for gasoline engines. A separate ICON system is required for diesel-powered Super Duty trucks.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWill my factory wheels fit after installing this system?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. The Stage 4 system is confirmed compatible with OEM wheels and tires. For aftermarket fitments, ICON recommends 17×8.5-inch wheels with 5-inch backspace and 6 mm offset, 18×9-inch wheels with 5.25-inch backspace and 6 mm offset, or 20×9-inch wheels with 5.25-inch backspace and 6 mm offset.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eHow does the CDC Valve damping adjustment work?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eEach shock on this Stage 4 system carries a CDC Valve with 10 compression damping settings, adjustable externally on the vehicle without removing the shock. Both the front remote reservoir shocks and the rear piggyback reservoir shocks include the CDC Valve.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eDoes installation require cutting, drilling, or welding?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eNo. The ICON Stage 4 system is a 100% bolt-on installation. No drilling, cutting, or welding is required. Note that Advanced Driver Assistance Systems (ADAS) require professional recalibration after the lift is installed, and trucks with Ford's OnBoard Scales system need an additional sensor bracket (ICON part 66203, sold separately).\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat is the largest tire this system will clear?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe fabricated radius arms on this Stage 4 system are profiled to clear a 37-inch tall tire at full steering lock without contact. ICON's recommended tire size is 35×12.50; 37×12.50 tires may fit but will require fender trimming and additional modifications.\u003c\/p\u003e","brand":"ICON Vehicle Dynamics","offers":[{"title":"Default Title","offer_id":50630884982854,"sku":"K65898R","price":5837.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0691\/2203\/1686\/files\/7b7ce8a8546b674dc06440bd832f245f-sq.jpg?v=1791963258","url":"https:\/\/terrainvault.com\/products\/icon-stage-4-2-5-inch-lift-suspension-system-with-radius-arms-for-2023","provider":"TerrainVault","version":"1.0","type":"link"}
