Air Lift LoadLifter 7500 XL Ultimate Air Spring Kit for 2020-2022 Ford F-250/F-350 Super Duty SRW 4WD (57552)

Fits select 2020-2022 Ford F-250 and F-350 Super Duty 4WD Single Rear Wheel (SRW) models. The Air Lift LoadLifter 7500 XL Ultimate air spring kit (MPN: 57552) provides up to 7,500 lbs. of load-leveling capacity to eliminate vehicle squat, trailer sway, and bottoming out. Designed for the heaviest towing applications, this system offers 20% more air spring volume than the LoadLifter 5000 series for superior ride support.

Constructed with 2-ply reinforced fabric air springs and ultra-high-strength nylon composite end caps, this kit is as durable as steel while remaining corrosion-proof. An integrated internal jounce bumper—made from closed-cell urethane foam—absorbs shock and prevents harsh jarring on rough roads, allowing the air springs to run safely with zero air pressure if necessary. This kit also includes upper and lower roll plates to protect the bellows from abrasion.
