Product Description
The AIR LIFT 57385 LoadLifter 5000 Air Spring Kit is designed to dramatically improve towing stability and load support for the 2015-2020 Ford F-150 4WD. Built for truck owners who tow trailers, haul equipment, or carry heavy cargo, this heavy-duty air suspension system delivers up to 5,000 pounds of load-leveling capacity to keep your truck level and stable under demanding conditions.
When towing heavy trailers or hauling cargo, the rear suspension of a truck can squat and reduce steering control and braking performance. The LoadLifter 5000 system installs between the frame and rear suspension to restore proper ride height and maintain balanced weight distribution across all four tires. The system is fully adjustable from 5 to 100 PSI, allowing drivers to match suspension support to the exact load they are carrying.
The AIR LIFT 57385 kit features rugged double-convoluted air springs built with reinforced two-ply rubber construction for maximum durability. Heavy-duty mounting brackets and protective roll plates help extend the life of the air springs while improving towing stability and ride comfort. The kit includes air springs, brackets, air lines, fittings, and installation hardware for a complete bolt-on upgrade.
