The kit is compatible with stock leaf springs, ICON F-150 Multi-Rate Leaf Springs, and most other aftermarket spring packs.\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.

The ICON shackles are CNC machined from 6061 aircraft-grade aluminum, a material that delivers greater strength-to-weight performance than the factory steel units. A gusseted design reinforces the shackle body at the bushing seats, maintaining proper clearance so the shackles cycle through full suspension travel without binding against stock or aftermarket leaf springs.\u003c\/p\u003e\n\n\u003ch2\u003e1-Inch Drop, Broad Spring Compatibility\u003c\/h2\u003e\n\u003cp\u003eAdding 1 inch of rear drop reduces the amount of front lift needed to bring the F-150 to a level stance, which simplifies front suspension tuning and can reduce the aggressive nose-up rake that often accompanies a front lift alone. The gusseted geometry is sized to clear stock leaf springs, ICON's own F-150 Multi-Rate Leaf Springs, and most other aftermarket spring packs, so the shackles work within a wide range of suspension configurations rather than locking the owner into a single setup.\u003c\/p\u003e\n\n\u003ch2\u003eMaintenance-Free Bushings, Finished to Last\u003c\/h2\u003e\n\u003cp\u003eEach shackle ships with pre-installed, press-in OE Ford bonded bushings. The bonded design requires no periodic greasing and operates without noise through the full range of suspension travel. Bushings are replaceable when worn. The satin gray anodized finish resists corrosion and holds up to the same off-road conditions the aluminum construction is built for.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1-Inch Rear Drop:\u003c\/strong\u003e lowers rear ride height to reduce front-lift requirement for a level stance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e6061 Aircraft-Grade Aluminum:\u003c\/strong\u003e CNC machined for greater strength than factory steel shackles\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGusseted Design:\u003c\/strong\u003e ensures proper bushing clearance for stock and most aftermarket leaf springs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePre-Installed OE Ford Bonded Bushings:\u003c\/strong\u003e maintenance-free, no greasing required, replaceable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSatin Gray Anodized Finish:\u003c\/strong\u003e corrosion-resistant surface treatment\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\u003e2010–2026 Ford F-150 (excludes 2021–2026 F-150 Raptor)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Drop\u003c\/td\u003e\n      \u003ctd\u003e1 inch\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMaterial\u003c\/td\u003e\n      \u003ctd\u003e6061 aircraft-grade aluminum\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFinish\u003c\/td\u003e\n      \u003ctd\u003eSatin gray anodized\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBushing Type\u003c\/td\u003e\n      \u003ctd\u003ePre-installed, replaceable OE Ford bonded bushings\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSpring Compatibility\u003c\/td\u003e\n      \u003ctd\u003eStock leaf springs, ICON F-150 Multi-Rate Leaf Springs, most aftermarket spring packs\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003e91001\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e8 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 kit suits 2010–2026 Ford F-150 owners who want to correct rear ride height, whether leveling the truck after a front lift, fine-tuning stance with aftermarket leaf springs, or reducing factory rake for a cleaner look on and off road.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis kit does not fit the 2021–2026 Ford F-150 Raptor.
