Product Description

The Air Lift 57577 LoadLifter 7500XL Ultimate is a rear air spring kit engineered for 2017-2019 Ford F-250/F-350 and 2017-2022 F-450 Super Duty 4WD trucks, delivering up to 7,500 lbs. of load-leveling capacity for the heaviest towing and hauling jobs. The massive 7-inch double-convoluted bellows provide 20% more air spring volume than the LoadLifter 5000 series, allowing stronger leveling performance at lower, more comfortable air pressures.

An internal jounce bumper absorbs shock even at zero PSI, while Air Lift's exclusive upper and lower roll plates protect the bellows from abrasion and boost load capacity by up to 10%. The 2-ply reinforced bellows and corrosion-proof nylon composite end caps are built for long-term durability, and installation uses the truck's existing frame holes for a bolt-on fit with no drilling required.

Backed by Air Lift's limited lifetime warranty, this LoadLifter 7500XL kit is built for Super Duty owners who need serious, adjustable load support for gooseneck and 5th wheel towing without sacrificing everyday ride comfort.
