Heavy trailers and bed loads can make the rear end sag, throwing off steering, braking, and headlight aim. The LoadLifter 5000 Ultimate air springs add up to 5,000 lbs of load-leveling capacity to keep your truck level from front to back. By sharing the weight across all four wheels, handling feels balanced and confident whether you’re towing a camper or hauling a full bed of gear. The adjustable setup helps maintain safe headlight aim and reduces strain on your factory suspension.
Uneven roads and heavy bumps can make towing a rough ride. Each LoadLifter 5000 Ultimate spring has an internal urethane jounce that cushions impacts and smooths out the ride when air pressure is low. These built-in jounces act as overload springs that engage progressively—the more you load them, the stiffer they become—so you get steady support without harshness. Even if pressure drops, the internal jounce lets you temporarily carry a load until the air system is adjusted.
Every haul is different, so having control over ride height matters. With a pressure range of 5–100 psi, you can fine-tune for the perfect balance between comfort and support. Inflate the springs for heavy loads or towing duty, then drop back down to 5 psi for a smoother unloaded ride. Manual inflation valves and air lines are included for easy setup, and the system can be paired with an optional in-cab compressor or wireless control for quick adjustments on the fly.
Durability counts when your suspension carries real weight. These air bags use 2-ply, fabric-reinforced rubber with corrosion-resistant Zytel nylon endcaps that are lighter and stronger than steel. Air Lift’s exclusive upper and lower roll plates guard against punctures from nearby components and improve spring rate at lower pressures for better ride quality. The urethane jounces require no maintenance and hold up in both hot and cold conditions, backed by a lifetime warranty with no mileage limit.
Installing serious load support doesn’t have to be complicated. The kit includes mounting brackets, hardware, manual inflation valves, and air lines for a clean DIY installation using hand tools. Once mounted, just inflate through the valves—typically located on the bumper—and you’re ready to go. The system works on its own or can be upgraded with an optional compressor kit for in-cab monitoring and automatic pressure control. It’s a practical, adjustable upgrade built for everyday hauling and towing.

I have removed the airbags from my vehicle and replaced them with a set of SumoSprings. I am much happier with the SumoSprings.

Saving money is always a bonus! I'm glad that even after a year you love the system so much. Here's to many more miles, Erik!

Thank you for your review. In order to monitor the air pressure in the Air Lift air bags you would need to install an air compressor system in the vehicle that monitors the air pressure and can automatically maintain the minimum air pressure. The Air Lift WirelessAIR Compressor System for Air Helper Springs part AL74000EZ automatically restores air pressure when it falls below a safe pressure. It also allows you to use your smart phone to adjust the pressure.

Lawrence, thank you for your review. The torque spec of the 3/*8 bolt is listed at the bottom of page 7 of the installation instructions. Since these figures are subject to change I cant list them here for liability reasons.

One year later and the air bags and wireless compressor are still running strong.
