Every component ships as a matched, dyno-tuned package: 2.5 Series CDCV remote reservoir coilovers up front, fabricated radius arms, an adjustable track bar, dual steering stabilizers, and CDCV piggyback reservoir rear shocks paired with leaf spring expansion packs. Springs are rated for diesel engines only. Fits single rear wheel models only; does not fit F-350\/F-450 Cab \u0026amp; Chassis configurations.\u003c\/p\u003e\n\u003cp class=\"product-shipping-note\"\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. 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\u003eExternal Damping Adjustment Without Disassembly\u003c\/h2\u003e\n\u003cp\u003eFront and rear shocks on the Stage 6 system carry ICON's CDC Valve, which provides 10 externally accessible compression damping settings ranging from soft to firm. Adjusting ride character to match a load, a road surface, or a towing situation takes seconds without removing a wheel or cracking a shock body. That tunability is especially useful on a truck that alternates between highway commuting and loaded work-site runs, where a single fixed damping rate is always a compromise.\u003c\/p\u003e\n\n\u003ch2\u003eRadius Arms That Solve Caster and Tire Clearance Together\u003c\/h2\u003e\n\u003cp\u003eICON's fabricated, fully boxed radius arms replace the factory units and address two problems simultaneously. On-vehicle caster adjustment is built into the arm itself, eliminating the need for caster bushings or drop brackets after the lift. The arm profile is optimized so that a 37-inch tall tire clears at full steering lock without contacting the radius arm. A sealed pivot bushing minimizes road noise transmitted into the cab and is designed for long service life without periodic rebuilding.\u003c\/p\u003e\n\n\u003ch2\u003eRear System Designed Around the F-250\/F-350 Leaf Pack\u003c\/h2\u003e\n\u003cp\u003eRather than replacing the factory rear leaf springs, the Stage 6 system adds ICON leaf spring expansion packs with blocks and U-bolts. The expansion packs increase compliance and reduce axle wrap under acceleration. On the F-250, the rear block arrangement adds approximately 0.5 inches of rear lift over stock. On the F-350, the same configuration lowers rear ride height by approximately 0.5 inches compared to stock (a meaningful distinction when spec-matching front and rear lift heights). ICON 2.5 Aluminum Series CDCV piggyback reservoir rear shocks and a 2-inch rear bump stop spacer kit complete the rear assembly.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCDCV Remote Reservoir Coilovers:\u003c\/strong\u003e 2.5 Series front coilovers adjustable for 2.5–3\" or 3.25–3.75\" of front lift depending on model year and option package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e10-Setting CDC Valve:\u003c\/strong\u003e external compression damping adjustment on front and rear shocks, from soft to firm, without disassembly\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFabricated Radius Arms:\u003c\/strong\u003e on-vehicle caster adjustment, sealed pivot bushing, and a profile that clears 37-inch tires at full steering lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable Track Bar:\u003c\/strong\u003e FK rod end for optimum front axle centering and minimal deflection\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual 2.0 Aluminum Series Steering Stabilizers:\u003c\/strong\u003e opposing-mount kit for smooth wheel control\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRear Leaf Spring Expansion Packs:\u003c\/strong\u003e blocks and U-bolts for improved compliance and reduced axle wrap; springs rated for diesel engines only\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\u003eFitment\u003c\/td\u003e\n      \u003ctd\u003e2017–2022 Ford F-250 \/ F-350 Super Duty 4WD, single rear wheel models only\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Lift: 2017–2019 Super Duty\u003c\/td\u003e\n      \u003ctd\u003e2.5–3\" over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Lift: 2020–2022 (non-Tremor)\u003c\/td\u003e\n      \u003ctd\u003e3.25–3.75\" over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Lift: 2020–2022 (Tremor package)\u003c\/td\u003e\n      \u003ctd\u003e2.25–2.75\" over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Lift: F-250\u003c\/td\u003e\n      \u003ctd\u003e+0.5\" over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Lift: F-350\u003c\/td\u003e\n      \u003ctd\u003e-0.5\" vs. stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Shock Series\u003c\/td\u003e\n      \u003ctd\u003e2.5 Aluminum Series CDCV remote reservoir (coilover + secondary)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Shock Series\u003c\/td\u003e\n      \u003ctd\u003e2.5 Aluminum Series CDCV piggyback reservoir\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDamping Adjustment\u003c\/td\u003e\n      \u003ctd\u003e10 external CDC Valve settings, front and rear\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSpring Rating\u003c\/td\u003e\n      \u003ctd\u003eDiesel engines only\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMax Tire Size (no modification)\u003c\/td\u003e\n      \u003ctd\u003e35\" x 12.50\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMax Tire Size (with fender trimming)\u003c\/td\u003e\n      \u003ctd\u003e37\" x 12.50\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003eK63146L\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e449 lb\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\"\u003eThe Stage 6 system suits owners of 2017–2022 Ford F-250 or F-350 Super Duty 4WD trucks with single rear wheels and diesel engines who want a fully integrated lift with external damping control, improved off-road compliance, and retained towing capacity. It is particularly well matched to trucks that see a mix of loaded highway driving, towing, and rough terrain.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis system does not fit F-350 or F-450 Cab and Chassis models, dual rear wheel configurations, or gas-engine Super Duty trucks (springs are rated for diesel only). It does not fit 2WD models. Advanced Driver Assistance Systems (ADAS) require professional recalibration after installation. The coil centering cup in the factory coil bucket must be removed during installation.
