Product Description
The AIR LIFT 57577 LoadLifter 7500 XL Air Spring Kit is engineered to deliver extreme load support for the 2014-2024 RAM 2500. Designed for heavy-duty towing and hauling applications, this premium air suspension system provides up to 7,500 pounds of load-leveling capacity, helping eliminate rear suspension squat, reduce trailer sway, and dramatically improve ride stability under heavy loads.
The LoadLifter 7500 XL system uses massive 7-inch double-bellows air springs that provide approximately 20% more air spring volume than standard LoadLifter 5000 systems. This increased volume allows the suspension to support larger loads with lower air pressure while maintaining excellent ride comfort. Drivers can fine-tune suspension support with adjustable air pressure from 5 to 100 PSI, ensuring optimal performance whether towing large trailers or hauling heavy equipment.
Each air spring features an internal jounce bumper that helps absorb shock and prevent bottoming out even if air pressure is low. Reinforced roll plates protect the air springs while distributing load evenly across the suspension system. The AIR LIFT 57577 kit includes air springs, mounting brackets, airlines, fittings, and installation hardware for a complete heavy-duty suspension upgrade.

FAQ
How much load support does the Air Lift 57577 provide?
The LoadLifter 7500 XL system provides up to 7,500 pounds of load-leveling support, making it ideal for heavy-duty towing such as fifth-wheel trailers and large equipment haulers.
What is the difference between LoadLifter 5000 and 7500 XL?
The 7500 XL uses larger 7-inch air springs with more air volume, allowing the system to support heavier loads with lower air pressure.
Can I install an onboard compressor system?
Yes. Air Lift compressor kits such as WirelessONE or WirelessAIR allow drivers to adjust air pressure from inside the cab.
Will this increase my truck’s payload rating?
No. Air spring kits improve suspension support and stability but do not increase the vehicle’s manufacturer-rated payload capacity.
Will these air springs improve towing stability?
Yes. Air springs maintain proper ride height, reduce trailer sway, and improve braking and steering control while towing heavy loads.
