The complete kit is 100% bolt-on, requiring no drilling, cutting, or welding. Springs are rated for diesel engines only. Lift heights are based on 4WD Crew Cab Diesel configuration.\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.

ICON engineered new progressive dual-rate coil springs specifically for this generation to achieve the correct 2.5-inch front lift rather than the over-tall result that earlier-generation components produce on these trucks. For buyers who want the advertised lift without an unintended stance change, that generation-specific calibration matters from day one.\u003c\/p\u003e\n\n\u003ch2\u003ePiggyback Reservoir Shocks for Sustained Performance\u003c\/h2\u003e\n\u003cp\u003eThe 2.5 Aluminum Series piggyback reservoir shocks, fitted front and rear, extend the duration of consistent damping by keeping fluid cooler during sustained heavy use. On a truck that tows, hauls, or runs rough construction-site terrain repeatedly, heat-induced fade is a real degradation in ride and control. The reservoir design addresses that directly. Shocks are fully rebuildable and re-tunable, so performance can be restored or adjusted over the life of the truck without replacing the entire unit.\u003c\/p\u003e\n\n\u003ch2\u003eRear Expansion Packs Reduce Axle Wrap Without Sacrificing Tow Capacity\u003c\/h2\u003e\n\u003cp\u003eThe rear leaf spring expansion packs, 1-inch cast blocks, U-bolts, and 2-inch rear bump stop spacer kit work together to improve rear compliance and reduce axle wrap, a common complaint on heavily loaded or frequently towed Super Dutys. Towing capacity is unchanged from stock. On F-250 models the rear blocks add 0.5 inches of rear lift over stock; on F-350 models the same blocks lower the rear ride height by 0.5 inches compared to stock.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiesel-specific dual-rate coil springs:\u003c\/strong\u003e progressive rate design achieves 2.5-inch front lift on 2020–2023 Super Duty diesel models\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.5 Aluminum Series piggyback reservoir shocks:\u003c\/strong\u003e vehicle-specific tuning front and rear; fully rebuildable and re-tunable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAlignment cams included:\u003c\/strong\u003e application-specific cams correct caster alignment; rare cases may require a 2.6-degree cam on one side for proper caster split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRear leaf spring expansion packs:\u003c\/strong\u003e blocks and U-bolts reduce axle wrap and improve rear compliance\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  \u003cli\u003e\n\u003cstrong\u003eLifetime spring guarantee:\u003c\/strong\u003e springs are guaranteed not to sag or break\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\u003e2020–2023 Ford F-250 \/ F-350 Super Duty, 4WD, Diesel, Single Rear Wheel\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Lift\u003c\/td\u003e\n      \u003ctd\u003e2.5 inches (4WD Crew Cab Diesel baseline; Tremor package trucks: 1.5 inches)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Lift (F-250)\u003c\/td\u003e\n      \u003ctd\u003e+0.5 inches 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 inches vs. stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Shocks\u003c\/td\u003e\n      \u003ctd\u003e2.5 Aluminum Series piggyback reservoir (part 67700P, qty 1 pair)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Shocks\u003c\/td\u003e\n      \u003ctd\u003e2.5 Aluminum Series piggyback reservoir (part 37705P, qty 1 pair)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCoil Springs\u003c\/td\u003e\n      \u003ctd\u003eDual-rate, diesel-optimized (part 62511, qty 1 kit)\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 (168507), 12-inch U-bolt kit (67004), 1-inch cast block kit (191201), 2-inch rear bump stop spacer kit (61002)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eAlignment Cams\u003c\/td\u003e\n      \u003ctd\u003eIncluded; application-specific for caster correction\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e305 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003eK62522L\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 2020–2023 Ford F-250 and F-350 Super Duty trucks in 4WD configuration with a diesel engine and single rear wheels, particularly owners who tow regularly, run rough terrain, or want a factory-correct 2.5-inch lift without fabrication work.

It is not compatible with all factory wheel and tire combinations; aftermarket wheels with lower offset or less backspace are recommended. An adjustable track bar (sold separately) may be needed to realign the axle, and a brake line kit (part 61111, sold separately) is optional for buyers who prefer not to bend the factory steel lines.

The factory steel brake lines can be retained and repositioned during installation; a braided stainless brake line kit (part 61111) is available separately for buyers who prefer not to bend the factory lines, but it is not required to complete the install.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWill this system work on my F-350 with dual rear wheels?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eNo. The ICON Stage 2 2.5-inch lift system for 2020–2023 Super Duty is rated for single rear wheel models only.

Rear lift figures remain the same: F-250 gains 0.5 inches over stock; F-350 sits 0.5 inches lower than stock with the included blocks.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eIs an adjustable track bar required?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eAn adjustable track bar is not included in the Stage 2 system but may be needed to realign the front axle from left to right after installation or to add additional strength. ICON track bar bracket part 64039 is also recommended to correct bump steer geometry.
