Air Lift LoadLifter 5000 Ultimate Air Spring Kit for 2017-2019 Ford F-250/F-350 Super Duty (88399)

Fits 2017-2019 Ford F-250 and F-350 Super Duty pickups; does not fit Cab & Chassis applications.

The Air Lift LoadLifter 5000 Ultimate air spring kit (MPN 88399) is engineered to provide up to 5,000 lbs. of load-leveling capacity for heavy-duty towing and hauling. This system features an industry-exclusive internal jounce bumper made of closed-cell urethane foam. This internal cushion allows the air springs to be run safely at zero air pressure, absorbs road shock, and prevents harsh jarring or bottoming out even on rough terrain. By working with your vehicle's leaf springs, it eliminates sag and sway while improving overall ride stability and steering control.

Constructed for maximum durability, the air springs are built like a tire with 2-ply reinforced fabric. The kit includes upper and lower roll plates to protect the bellows from sharp edges and increase overall load capacity. Installation is designed to be straightforward with a no-drill design that bolts to factory mounting points, replacing the factory jounce bumpers.
