When you hitch up a trailer or stack the bed full of gear, rear-end sag can throw off your steering and braking. The Air Lift LoadLifter 5000 Ultimate air springs add up to 5,000 lbs of load-leveling capacity to keep your truck level front to back and maintain proper headlight aim. By distributing weight to all four wheels, they help reduce stress on your factory suspension and improve handling and tire wear when hauling or towing heavy loads.
Rough pavement and uneven loads can make for a harsh ride. Each LoadLifter 5000 Ultimate air spring has a closed-cell urethane jounce spring inside that kicks in when air pressure alone isn’t enough. These jounces engage progressively—the more weight you add, the stiffer they become—to absorb bumps, minimize bottoming out, and reduce sway through turns. Even with low air pressure or zero PSI, the jounce springs step in as a fail-safe to keep your suspension protected.
From an empty bed to a fully loaded trailer, every haul demands different support. These air springs let you fine-tune ride height and firmness anywhere between 5 psi and 100 psi. Inflate both sides equally for front-to-back leveling or adjust them independently to balance off-center loads. Manual inflation valves and air lines are included, with optional compressor systems available if you want in-cab control for quick adjustments on the go.
Durability matters when you’re counting on suspension support day after day. Each LoadLifter 5000 Ultimate bag uses 2-ply, fabric-reinforced rubber with high-strength Zytel nylon endcaps that are lighter, stronger, and more corrosion-resistant than steel. Air Lift’s exclusive roll plates guard against damage from nearby parts while adding surface area for better spring rate at lower pressure. Urethane jounce springs require no maintenance and perform reliably in hot or cold conditions, backed by a lifetime warranty with no mileage restrictions.
Installing serious suspension support doesn’t have to be complicated. The kit comes with all mounting brackets, hardware, manual inflation valves, and airline fittings needed for setup using basic tools. Once installed, you can inflate the bags right from the bumper for easy access or upgrade later to an onboard compressor system for automatic control. The straightforward design makes it a practical choice for anyone who likes to wrench on their own truck.

After a year of hard use this product has held up really well. My only regret is not buying it sooner. For my application 2013 Ford F150, wrapping the exhaust in a heat shielding tape is a must.

Product works great and helps level the truck during towing. I have noticed a difference in the amount of travel my back wheels have when offloading. But I knew that would be a sacrifice.

Glad to hear the install went smoothly! Thanks for the suggestion on the brake line/ABS brackets too. Definitely something that could make a good kit even better!

For the ABS brake wire, I would use a zip tie to maneuver it out of the way of that bolt you mention. My contact at Airlift assured me that the heat shield will protect the air bags and air lines within 1 inch of the exhaust. I would route the air line as far as possible away, securing with zip ties.
