LoadLifter 5000 04-14 Ford F150 4WD

The Air Lift LoadLifter 5000 air spring kit for 2004–2014 Ford F-150 4WD trucks delivers 5,000 pounds of leveling capacity to the rear axle, restoring factory ride height under heavy load and eliminating squat during towing or hauling. This bolt-on air suspension system combines air springs, brackets, and pneumatic lines in a complete package designed specifically for full-size Ford trucks, making it the go-to upgrade for owners who regularly carry payload or pull trailers and refuse to drive nose-up.

The kit includes heavy-duty air springs that mount to the rear leaf springs, black powder-coat steel brackets that resist corrosion, and all necessary lines and fittings for straightforward installation on Ford F-150 models across the 2004–2014 production years. The 5,000-pound capacity handles serious work—loaded tool boxes, camper shells, gooseneck trailers, and payload racks—without allowing the frame to sag or the rear end to bottom out over bumps. The air suspension maintains consistent geometry and ride quality whether the truck is empty or at GVWR, preventing brake imbalance and suspension damage that occurs when springs are permanently compressed.

This LoadLifter 5000 kit is engineered for Ford F-150 owners who work their trucks—contractors, ranchers, off-road enthusiasts, and anyone towing or hauling regularly. Unlike passive add-a-leaf kits that permanently raise ride height and stiffen the suspension, air springs adjust on demand: deflate them for empty-truck comfort, inflate for load support. The modular design allows DIY installation or professional fitting at a shop, and the sealed air system requires minimal maintenance beyond occasional hose inspection. For F-150 4WD operators seeking load-leveling performance without permanent stiffness or ride quality loss, the Air Lift LoadLifter 5000 is the industry standard.
