Stay Level and Confident Under Load: Up to 5,000 lbs of Rear Suspension Support
When you’re hauling or towing heavy weight, sagging suspension can throw off your braking, steering, and headlight aim. The Air Lift LoadLifter 5000 Ultimate air springs add up to 5,000 lbs of load-leveling capacity to keep your vehicle level front to back and side to side. This setup shares the load across all four wheels for improved control and more even tire wear under pressure.
Smooth Out the Ride: Internal Jounce Springs Absorb Shock and Prevent Bottoming Out
Rough roads and heavy cargo can make your rear end bounce or bottom out. Each LoadLifter 5000 Ultimate air spring has a closed-cell urethane jounce spring inside that kicks in automatically when air pressure isn’t enough to handle the load. These internal jounces engage gradually, softening bumps and helping with cornering and sway while keeping your ride comfortable even when carrying serious weight.
Dial In Your Setup: Adjustable 5–100 psi Air Pressure for Any Load
Every trip is different, so it helps to be able to fine-tune your suspension on demand. These air springs adjust from 5 psi up to 100 psi for precise load support. You can inflate both sides equally for front-to-back leveling or adjust them independently for side-to-side balance on uneven loads. Manual inflation valves and air lines are included, and the system is compatible with on-board compressor upgrades if you want in-cab control.
Built Tough for the Long Haul: Reinforced Construction and Protective Details
Durability matters when you depend on your suspension every day. The LoadLifter 5000 Ultimate uses 2-ply, fabric-reinforced rubber air springs with high-strength Zytel nylon endcaps that are lighter, stronger, and more corrosion resistant than steel. Exclusive roll plates protect the bags from contact damage while adding extra load capacity. With maintenance-free urethane jounces inside and heavy-duty mounting brackets included, this system is built for long-lasting performance through miles of real work.
Simple DIY Installation: Brackets, Hardware, and Valves Included
Installing real suspension support doesn’t have to be a shop job. The kit includes mounting brackets, hardware, manual inflation valves, and air lines so you can set it up with basic tools. Once installed, you can inflate through easy-access bumper-mounted valves or upgrade later with an optional compressor system for automatic monitoring and adjustments.

After a year of using the bags I still couldn’t be happier. Air level holds and still the best ride that van has ever been
