The complete bolt-on kit includes dual-rate coil springs, fabricated radius arms, ICON 2.5 Aluminum Series piggyback reservoir shocks front and rear, rear leaf spring expansion packs, U-bolts, a cast block kit, and a rear bump stop spacer kit. This system is available in one configuration sized for single-rear-wheel models only.\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\u003eEngineered as a Complete Package\u003c\/h2\u003e\n\u003cp\u003eThe Stage 2 system brings together springs, shocks, radius arms, and rear expansion packs developed and tuned by ICON as a matched set rather than assembled from separate part numbers. The dual-rate coil springs and 2.5 Aluminum Series piggyback reservoir shocks are calibrated to work together, so ride and handling characteristics reflect the full system rather than the compromise of mixing components. For a truck used across towing, job-site work, and off-road driving, a purpose-tuned package removes the guesswork of building a lift piecemeal.\u003c\/p\u003e\n\n\u003ch2\u003eRadius Arms Built for Clearance and Longevity\u003c\/h2\u003e\n\u003cp\u003eThe fabricated, fully-boxed radius arms include a sealed pivot bushing that reduces road feedback and resists wear over time. The arm profile is optimized for tire clearance at full steering lock, allowing a 37-inch-tall tire to clear the radius arm without contact. This is a meaningful advantage when fitting larger rubber on a work or overland truck. The radius arm design also allows on-vehicle caster adjustment, so alignment can be dialed in after installation without pulling the system apart.\u003c\/p\u003e\n\n\u003ch2\u003eRear Compliance Without Sacrificing Tow Capacity\u003c\/h2\u003e\n\u003cp\u003eThe rear leaf spring expansion packs, blocks, and U-bolts address axle wrap and ride harshness that stock rear springs produce under load cycling. ICON states the system produces less body roll than stock with no reduction in towing capacity. On F-250 models the rear blocks add 0.5 inches of lift over stock. On F-350 models the same blocks lower rear ride height by 0.5 inches compared to stock, a distinction worth confirming when specifying the system for a particular truck.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual-rate coil springs:\u003c\/strong\u003e gas-engine-optimized, rated to provide 2.5 inches of front lift over stock; lifetime guarantee against sag or break\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 full steering lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eICON 2.5 Aluminum Series shocks:\u003c\/strong\u003e piggyback reservoir, front and rear, fully rebuildable and re-tunable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRear expansion packs:\u003c\/strong\u003e leaf spring expansion packs, U-bolts, cast block kit, and bump stop spacer kit included\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100% bolt-on installation:\u003c\/strong\u003e no drilling, cutting, or welding required; 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\u003eVehicle Fitment\u003c\/td\u003e\n      \u003ctd\u003e2023–2026 Ford F-250 \/ F-350 Super Duty, 4WD, gasoline engine, single rear wheel\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Lift Height\u003c\/td\u003e\n      \u003ctd\u003e2.5 inches over stock (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\u003eRear Lift Height\u003c\/td\u003e\n      \u003ctd\u003eF-250: +0.5 in over stock | F-350: −0.5 in vs. 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 piggyback reservoir (part 67700P)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Shocks\u003c\/td\u003e\n      \u003ctd\u003eICON 2.5 VS piggyback reservoir (part 37705P)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCoil Springs\u003c\/td\u003e\n      \u003ctd\u003eDual-rate, gas-engine-optimized (part 62517)\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 (part 64043)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Components Included\u003c\/td\u003e\n      \u003ctd\u003eLeaf spring expansion packs ×2 (part 168507), 12-inch U-bolt kit (part 67004), 1-inch cast block kit (part 191201), 2-inch rear bump stop spacer kit (part 61002)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e386 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003eK65896RL\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 owners of 2023–2026 Ford F-250 or F-350 Super Duty trucks with four-wheel drive, a gasoline engine, and single rear wheels who want a 2.5-inch front lift with meaningfully improved ride quality for towing, job-site use, and off-road driving, and who want a complete, matched component set rather than sourcing parts individually.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis system does not fit diesel-engine Super Duty trucks, two-wheel-drive models, dual-rear-wheel (dually) configurations, or F-350 Cab and Chassis models. Not all factory wheel and tire combinations are compatible; aftermarket wheels with lower offset are recommended. Trucks equipped with the Tremor package will see approximately 1.5 inches of front lift rather than 2.5 inches. Trucks with OnBoard Scales require an additional sensor bracket (ICON part 66203). Trucks with Dynamic Bending Headlamps and\/or OnBoard Scales also require ICON part 611081. An adjustable track bar (ICON part 64039) is recommended to correct bump steer geometry. Advanced Driver Assistance Systems (ADAS) require recalibration after installation.

The dual-rate coil springs in this kit are rated for gas engines. Diesel-engine Super Duty owners require a separate ICON system calibrated for the additional front-end weight of a diesel powertrain.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWill this system work on a dually (dual-rear-wheel) F-350?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eNo. The ICON Stage 2 suspension system K65896RL fits single-rear-wheel models only.

Trucks with OnBoard Scales require ICON sensor bracket part 66203. Trucks with Dynamic Bending Headlamps and\/or OnBoard Scales also require ICON part 611081. ICON track bar bracket part 64039 is recommended to correct bump steer geometry. An adjustable track bar may also be needed to realign the axle. ADAS systems require professional recalibration after installation. A braided stainless brake line kit (ICON part 61111) is optional.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat tire size fits with the radius arms at full steering lock?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe ICON fabricated radius arms in this Stage 2 system are profiled to clear a 37-inch-tall tire at full steering lock without contact. ICON recommends 35×12.50-inch tires as the primary fitment; 37×12.50-inch tires may fit but fender trimming and modifications will be required. Not all factory wheel and tire combinations are compatible, and aftermarket wheels with lower offset are recommended.\u003c\/p\u003e","brand":"ICON Vehicle Dynamics","offers":[{"title":"Default Title","offer_id":50631687274566,"sku":"K65896RL","price":5679.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0691\/2203\/1686\/files\/692c11fb0884b0d0c5c406a6d5cb645f-sq.jpg?v=1791967089","url":"https:\/\/terrainvault.com\/products\/icon-stage-2-suspension-system-with-radius-arms-for-2023-2026-ford-f-2","provider":"TerrainVault","version":"1.0","type":"link"}
