Fits select 2019-2025 Ram 3500 and 2020-2021 Ram ProMaster 3500 models (Excludes Cab & Chassis models).

The Air Lift LoadLifter 7500 XL Ultimate air spring kit (MPN: 57531) is engineered for heavy-duty towing and hauling, providing up to 7,500 lbs. of load-leveling capacity. This system features 7-inch double bellows air springs that offer 20% more air volume than the LoadLifter 5000 series, significantly reducing rear-end sag, trailer sway, and body roll while maintaining steering and braking control.

A standout feature of the Ultimate series is the integrated, closed-cell urethane foam jounce bumper. This internal bumper absorbs shock on rough roads and allows the air springs to be run safely at zero air pressure if needed. Construction includes 2-ply fabric-reinforced springs for maximum durability and ultra-high-strength nylon composite end caps that are as strong as steel but completely corrosion-proof.
