Upgrade Your Rear Suspension Without Sacrificing Comfort

If your truck rides rough after a leveling kit, the Carli Full Progressive Deaver Leaf Packs are exactly what you need to smooth things out without giving up load support. Designed specifically for 2011-2016 Ford F-250 and F-350 4WD trucks with 2.5 to 4.5 inches of lift, these leaf packs transform the way your Super Duty handles the road. Unlike the harsh factory setup, Carli’s custom-tuned Deaver springs offer a supple, controlled ride whether your bed is empty or you're hauling a load. You get better travel, more stability, and a truck that feels planted and responsive without beating you up on every bump. The progressive design means the springs work with you as weight is added, giving you support when you need it and comfort when you don’t. Whether you're on pavement, loaded down with gear, or exploring off-road trails, the difference in ride quality is night and day. It's a premium upgrade that delivers real-world performance for daily drivers and weekend warriors alike.

Built For Travel Articulation And Ride Consistency

The Carli CS-FFSP-LVL-11 Full Progressive Deaver Leaf Packs are engineered to provide optimal performance for leveled Ford Super Duty trucks running 2.5 to 4.5 inch Carli suspension systems. Developed in partnership with Deaver Spring, this 9-leaf main pack and 3-leaf progressive overload combination significantly increases suspension travel while improving ride predictability and control. Compared to the factory leaf springs, which rely on stiff main leaves and a harsh static overload, this progressive setup allows the rear suspension to compress more smoothly under load. The design maintains much of the original towing and hauling capacity while offering a softer, more manageable ride when the truck is unloaded. Each spring is tuned to work in harmony with Carli’s leveling systems, ensuring proper geometry, articulation, and balance. This is a direct bolt-in solution, requiring no additional fabrication or modification to install. For anyone seeking greater off-road performance or day-to-day comfort without compromising capability, this spring pack strikes the perfect balance.
