1999-2004 Superduty Rear Loadlifter 5000 Air Spring Kit (ALF57390)

Restore the hauling confidence of your 1999-2004 Ford Super Duty with the Air Lift LoadLifter 5000 air spring kit. As these legendary trucks age, factory leaf springs can often fatigue under heavy loads; this kit provides up to 5,000 lbs. of load-leveling capacity to bring your F-250 or F-350 back to a level, stable ride height. By installing these heavy-duty air springs between your frame and rear axle, you eliminate the sag, trailer sway, and bottoming out that compromise safety. Whether you’re towing a vintage fifth-wheel or hauling heavy equipment to the job site, the LoadLifter 5000 ensures your Super Duty maintains optimal steering and braking control for a more comfortable, stress-free experience.
