Why this kit
Air Lift sells the springs and the compressor as separate part numbers, so most F-150 owners end up ordering twice or airing bags up at a gas station. This kit puts the two halves together at the value price point: the LoadLifter 5000 Ultimate rear air springs for the fourteenth-generation F-150, rated to level up to 5,000 lb of trailer pin weight, slide-in camper or bed load, and the LoadController II single-path compressor with a dash-mounted gauge and switch. Both springs inflate together from the cab, which is all a centered trailer or bed load needs. The Ultimate springs have an internal jounce bumper so they can run at zero pressure when the truck is empty without damage.

Questions
Single path or dual path?
Single path inflates both springs together to the same pressure, right for a centered bumper-pull or gooseneck load. If your load sits off to one side, the WirelessAir V2 version of this kit runs each side independently.
Does this raise my payload or tow rating?
No. Air springs level the truck and restore ride height and headlight aim under load. Your GVWR and tow ratings do not change.
Can I run the bags empty?
Yes. The Ultimate series has an internal jounce bumper that protects the spring at zero pressure.
How long does installation take?
The springs are a 1 to 2 hour bolt-in on the F-150 leaf pack with no drilling. The compressor and gauge are another 1 to 2 hours for mounting, wiring to a fused 12V source and routing air line to the dash.
What is the warranty?
Air Lift covers the air springs with a limited lifetime warranty and the compressor system for 2 years. Warranties are processed through the original place of purchase, so keep your Hannah Suspension order confirmation.
