Air Lift – LoadLifter 7500 XL Ultimate Rear Air Spring Kit – 2003–2018 Ram 2500/3500 4WD – 57595

The Air Lift LoadLifter 7500 XL Ultimate Air Spring Kit (57595) is designed to handle extreme towing and hauling demands on 2003–2018 Ram 2500 and 3500 4WD trucks, delivering up to 7,500 lbs. of load-leveling capacity. This heavy-duty rear air spring system helps eliminate squat, reduce trailer sway, improve braking performance, and prevent bottoming out when hauling or towing heavy loads.

As part of Air Lift’s Ultimate series, this kit features an internal jounce bumper, allowing the air springs to be safely operated at zero PSI without damage—providing full-time support even when unloaded. The LoadLifter 7500 XL levels heavy loads using less air pressure, improving ride quality while reducing stress on factory suspension components.

This system installs with no drilling required and is compatible with single rear wheel (SRW) and dual rear wheel (DRW) trucks. It fits all models without a fifth-wheel hitch, works with factory in-bed hitch systems, and is compatible with most side-mount fifth wheel hitch applications, making it a versatile solution for work and towing setups.
