Rock Krawler F2AS4004 4.0in Adventure Series Suspension System Lift Kit

The Rock Krawler F2AS4004 4.0-inch Adventure Series Suspension System is a complete lift kit engineered specifically for the 2011–2016 Ford F-250/F-350 6.7L Powerstroke diesel. Designed to deliver a dramatic improvement in both on-road ride quality and off-road capability, this system provides a full 4 inches of lift without sacrificing the drivability or handling characteristics that SuperDuty owners depend on every day.

Unlike generic spacer-style lift kits, the Rock Krawler Adventure Series utilizes custom-wound front coil springs that are precision engineered to properly support the weight of a diesel-powered SuperDuty while delivering a noticeably smoother and more controlled ride. The system maintains proper front-end geometry to minimize wear on steering and drivetrain components at ride height.

Key Features:

• 4.0-inch front and rear lift for increased ground clearance
• Custom-wound front coil springs engineered for diesel truck weight
• Improved steering geometry maintained at lifted ride height
• Allows fitment of larger aggressive tires
• Improved on-road and off-road ride quality vs. factory suspension
• Compatible with optional Rock Krawler Prodigy remote reservoir shock upgrade
• Bolt-on installation using factory mounting locations
• Manufactured in the USA by Rock Krawler Suspension

The Adventure Series system is built for SuperDuty owners who want a reliable, well-engineered lift that performs equally well on the highway, worksite, or trail. Shocks are not included and must be purchased separately; Rock Krawler's Prodigy 2.625-inch remote reservoir shocks are a highly recommended pairing for maximum performance.
