The complete bolt-on kit requires no drilling, cutting, or welding and includes rear leaf spring expansion packs, radius arms, track bar, and dual steering stabilizers.\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.

A driver hauling a loaded trailer can dial toward the firm end of the range. The same truck running empty on a washboard road can move toward soft, without removing a wheel or opening the hood. That range of on-the-fly control is what separates a tunable system from a fixed-valved shock swap.\u003c\/p\u003e\n\n\u003ch2\u003eReservoir Cooling for Sustained Performance\u003c\/h2\u003e\n\u003cp\u003eThe 2.5 Aluminum Series front shocks use remote reservoirs; the rear shocks use piggyback reservoirs. Both designs move fluid volume away from the main shock body, extending the period of consistent damping before heat-induced fade sets in. For a diesel Super Duty that spends time on rough construction roads or loaded highway miles, that thermal headroom translates to predictable handling deeper into a run rather than a gradual softening as shocks heat up.\u003c\/p\u003e\n\n\u003ch2\u003eRadius Arms and Track Bar Built Into the System\u003c\/h2\u003e\n\u003cp\u003eThe fabricated, fully boxed ICON radius arms include a sealed pivot bushing and on-vehicle caster adjustment, eliminating the need for separate caster bushings or drop brackets. Their profile is optimized for tire clearance at full steering lock, accommodating up to 37-inch-tall tires without contact. The adjustable front track bar with FK rod end centers the front axle and minimizes deflection. Both components are engineered and tuned as part of this complete package rather than sourced separately.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.5-inch front lift:\u003c\/strong\u003e dual-rate coil springs engineered for diesel engine weight, with a lifetime guarantee against sag or breakage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e10-position CDC Valve adjustment:\u003c\/strong\u003e external compression damping tuning on both front remote reservoir and rear piggyback reservoir 2.5 Aluminum Series shocks\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFabricated radius arms:\u003c\/strong\u003e fully boxed design with on-vehicle caster adjustment and a profile cleared for 37-inch tires at full steering lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable front track bar:\u003c\/strong\u003e FK rod end for optimum axle centering with minimal deflection\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual steering stabilizer kit:\u003c\/strong\u003e paired ICON 2.0 Aluminum Series stabilizers for smooth wheel control\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRear leaf spring expansion packs:\u003c\/strong\u003e blocks and U-bolts included for more compliant rear ride and reduced axle wrap; no driveshaft modifications 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\u003eFitment\u003c\/td\u003e\n      \u003ctd\u003e2011–2016 Ford F-250 \/ F-350 Super Duty 4WD Diesel, single rear wheel only\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront lift\u003c\/td\u003e\n      \u003ctd\u003e2.5 in 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 in over stock (replaces OE rear blocks)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear lift (F-350)\u003c\/td\u003e\n      \u003ctd\u003e−0.5 in vs stock (replaces OE rear blocks)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront shocks\u003c\/td\u003e\n      \u003ctd\u003e2.5 Aluminum Series CDCV remote reservoir, 0–2.5 in range (pair)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear shocks\u003c\/td\u003e\n      \u003ctd\u003e2.5 Aluminum Series CDCV piggyback reservoir, 0–3 in range (pair)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDamping adjustment\u003c\/td\u003e\n      \u003ctd\u003e10-position external CDC Valve, front and rear\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSpring type\u003c\/td\u003e\n      \u003ctd\u003eDual-rate coil springs, diesel-rated\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSteering stabilizers\u003c\/td\u003e\n      \u003ctd\u003eICON 2.0 Aluminum Series, dual opposing (qty 2)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOEM wheel\/tire fitment\u003c\/td\u003e\n      \u003ctd\u003eYes\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended aftermarket tire\u003c\/td\u003e\n      \u003ctd\u003eUp to 35 × 12.50 in (larger may require fender trimming)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInstallation\u003c\/td\u003e\n      \u003ctd\u003e100% bolt-on; no drilling, cutting, or welding; no driveshaft modifications\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003eK62586\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping weight\u003c\/td\u003e\n      \u003ctd\u003e436 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\"\u003eThis Stage 6 system suits owners of 2011–2016 Ford F-250 or F-350 Super Duty 4WD Diesel trucks on single rear wheel configurations who want a complete, tunable lift solution for towing, work-site terrain, and mixed on- and off-road use without fabrication work.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis system does not fit F-350 Cab \u0026amp; Chassis models, dual rear wheel configurations, gasoline-engine Super Duty trucks, or any model year outside 2011–2016.

F-350 Cab \u0026amp; Chassis and dual rear wheel models are not compatible. Note that rear lift differs by model: the F-250 gains approximately 0.5 inches over stock, while the F-350 sits approximately 0.5 inches lower than stock at the rear.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eAre the springs in this kit rated for diesel engines?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. The dual-rate coil springs in this Stage 6 system are specifically rated for diesel engine weight. They are not rated for gasoline-engine Super Duty applications, and ICON carries a lifetime guarantee that these springs will not sag or break under normal use.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eHow does the CDC Valve damping adjustment work?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe CDC Valve on the front remote reservoir and rear piggyback reservoir shocks provides 10 positions of external compression damping adjustment, ranging from soft to firm. Adjustment is made from outside the vehicle without removing wheels or disassembling any component, allowing the driver to tune ride character for towing, rough terrain, or highway cruising.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eIs any cutting, welding, or drilling required to install this kit?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eNo. The ICON Stage 6 Suspension System is a 100% bolt-on kit. No drilling, cutting, or welding is required, and no driveshaft modifications are needed.
