The Air Lift LoadLifter 7500 XL Ultimate is a rear load-leveling helper air spring kit for the 2023-2025 Ford F-450 4WD DRW (Non-Commercial). It adds up to 7,500 lbs of leveling capacity with a pair of 7-inch double-convoluted bellows air springs that level at lower pressures than smaller systems, adjustable from 5-100 PSI to control squat, trailer sway, and bottoming out. An internal closed-cell jounce bumper lets the springs run safely at zero PSI, and roll plates plus composite end caps add protection. The underframe kit bolts on with common hand tools and no frame drilling, working with most in-bed hitches.
