Take control of heavy loads, trailers, overland gear, and demanding terrain with the Air Lift LoadLifter 5000 Ultimate with Air Spring Cradles. Specifically engineered for the RAM TRX and RAM RHO, this premium rear air spring system delivers up to 5,000 pounds of load-leveling capacity, helping eliminate rear-end squat, trailer sway, body roll, and bottoming out while maintaining exceptional ride quality.
Whether you're towing a toy hauler, hauling equipment, carrying a rooftop tent, or loading your truck for a long overland adventure, maintaining proper ride height is critical for vehicle stability and safety. The LoadLifter 5000 Ultimate helps keep your RAM level under load, improving steering response, braking performance, tire wear, and overall driving confidence.
What separates this system from traditional air bag kits is Air Lift's exclusive Air Spring Cradle Technology. Unlike conventional air springs that can limit suspension droop, the Air Spring Cradles allow the air bags to detach from the lower mount during full suspension extension. This maintains maximum suspension articulation and wheel travel, making it an ideal solution for overland, trail, and off-road applications.
Inside each air spring is Air Lift's exclusive internal jounce bumper, providing progressive load support and three-stage ride comfort. The jounce bumper helps absorb harsh impacts, reduce bottoming out, and can safely support the vehicle even at zero PSI, offering an extra level of confidence on rough roads and demanding terrain.
The adjustable air spring design allows pressures from 5 to 100 PSI, giving you complete control over ride quality and load support. Add air when towing or hauling heavy cargo, then reduce pressure for a comfortable unloaded ride. This flexibility makes the system ideal for trucks that regularly transition between work, recreation, and daily driving duties.
Built for long-term durability, the LoadLifter 5000 Ultimate features heavy-duty reinforced air springs, corrosion-resistant hardware, and components tested to withstand extreme operating conditions. Installation requires no drilling into the frame and is compatible with most in-bed hitch systems.
Whether your RAM TRX or RHO is used for towing, overlanding, hauling gear, or off-road adventures, the LoadLifter 5000 Ultimate with Air Spring Cradles provides the support, control, and suspension performance needed to handle every journey with confidence.
