This "Air Lift Load Lifter 5000 Ultimate Plus" Helper Spring Kit is designed with the highest quality, longest lasting components available in a suspension air bag kit. This kit features high-grade stainless-steel roll plates, braided stainless-steel air lines and stainless-steel mounting hardware. Coupled with an internal jounce bumper inside the air spring for added support and ride comfort, the Ultimate Plus by Air Lift is top of the line.
This air spring kit will keep the rear end of your Ford F450 from sagging when towing or carrying a heavy load. These simple-to-install suspension upgrades mount between the rear leaf springs and chassis to increase your level load capacity up to 5,000 lbs. while leveling your truck with the power of air pressure. All Air Lift air bag helper springs are custom fit for a simple bolt-on installation. An optional air control kit (air compressor kit) can be added (not required) for additional convenience.
The internal jounce makes the difference here. This exclusive feature included in the Load Lifter 5,000 Plus gives you additional support and comfort not found in other suspension air bags. Made of a closed-cell urethane foam, it helps to eliminate harsh jarring and provides 3 stage ride comfort. This added cushion of air from the internal jounce also helps to protect the air bags when running very low pressure. Add in the stainless-steel components and you have the Ultimate Air Spring Kit.
All Air Lift air bag helper springs are backed by the Air Lift exclusive "60 Day Ride Satisfaction Guarantee" and a "Limited Lifetime Warranty".
