Air Lift LoadLifter 5000 ULTIMATE Air Spring Kit with Internal Jounce Bumper

The Air Lift LoadLifter 5000 Ultimate is Air Lift's flagship air spring kit line, purpose-built for trucks and vans that demand the highest level of load support, ride comfort, and towing confidence. Designed to integrate seamlessly with existing leaf spring suspension systems, LoadLifter 5000 Ultimate kits eliminate squat, sway, and bottoming out when hauling heavy cargo or towing trailers, fifth-wheels, and campers.

Exclusive Internal Jounce Bumper Technology:

What sets the LoadLifter 5000 Ultimate apart from every other air spring kit on the market is Air Lift's proprietary internal jounce bumper—a closed-cell urethane foam insert integrated directly inside each air spring. This Air Lift exclusive delivers a three-stage ride quality by absorbing shock and vibration from rough roads and uneven terrain. It also enables safe operation even at zero air pressure, and replaces the factory jounce bumper that is sometimes removed during air spring installation, keeping the suspension system fully protected at all times.

Key Features:

• Up to 5,000 lbs. of rear load-leveling capacity for demanding hauling and towing applications
• Fully adjustable air pressure from 5 to 100 PSI for precise tuning to any load condition
• 2-ply fabric-reinforced air springs built using tire-building technology for exceptional durability and long service life
• Ultra high-strength nylon composite end caps that are corrosion-resistant and built for harsh environments
• Exclusive upper and lower roll plates protect air springs from sharp edges and increase load capacity by up to 10%
• Compatible with vehicles equipped with in-bed hitches
• Restores level ride height and maintains proper steering and braking performance under load
• Maintenance-free design with safe zero-pressure operation courtesy of the internal jounce bumper
• Most applications require no drilling into the frame

What's Included:

Each vehicle-specific kit includes a pair of heavy-duty air springs with integrated internal jounce bumpers, application-specific mounting brackets, upper and lower roll plates, air lines, Schrader inflation valves, all necessary hardware, and fully illustrated installation instructions. Most kits are designed to install in two hours or less using common hand tools.

On-Board Compressor Compatible:

LoadLifter 5000 Ultimate kits are fully compatible with Air Lift's complete lineup of on-board air compressor systems, allowing drivers to adjust air pressure from inside or outside the vehicle for maximum convenience on the road.

Industry-Leading Warranty:

Air Lift backs every LoadLifter 5000 Ultimate kit with an industry-exclusive 60-day no-questions-asked money-back guarantee and a lifetime warranty—the most comprehensive in the industry—covering all kit contents including brackets, fittings, and air lines. All key suspension components are torture-tested to one million cycles on a hydraulic test rig, reflecting Air Lift's decades of engineering expertise and commitment to quality.
