When you’re towing a trailer or hauling heavy gear, rear-end sag can throw off your braking and steering. The Air Lift LoadLifter 5000 Ultimate Air Helper Springs give your suspension up to 5,000 lbs of load-leveling support so your truck stays level and under control. Adjustable air pressure from 5 psi to 100 psi lets you match support to the weight you’re carrying and keep your headlights aimed right where they should be.
Big bumps and uneven roads don’t have to mean a harsh ride. Each LoadLifter air spring has a closed-cell urethane jounce spring inside that engages progressively as weight increases. That extra cushion helps absorb shocks, reduce sway, and improve cornering. Even if your air pressure drops, the internal jounce springs step in as a fail-safe so you can keep driving without bottoming out.
These air springs are built for years of towing and hauling. The 2-ply, fabric-reinforced rubber bags pair with corrosion-proof Zytel nylon endcaps that are lighter and stronger than steel. Air Lift’s exclusive roll plates guard the bags from moving parts and add surface area for better ride quality at lower pressures. Every part is made to handle tough conditions without leaks or corrosion getting in the way.
Dialing in your suspension is straightforward with the included inflation valves and air lines. You can mount the valves on the bumper for easy access or pair the springs with an onboard compressor system (sold separately) for in-cab control. Brackets and hardware come with the kit so you can mount the springs, inflate them, and hit the road without complicated modifications.
The LoadLifter 5000 Ultimate kit is made for long-term use with no mileage limits. It includes a lifetime warranty and a 60-day satisfaction guarantee, so you can haul heavy trailers or campers knowing your suspension support is built to last.

Great, used it last Summer hauler 18’ trailer full of Harley’s to Sturgis! I could not image doing it without the airbags. Highly recommend if you plan to haul heavy loads.

The air suspension bags work very well on leveling the truck and making for a more stable ride. Would do it again, very satisfied.

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!
