When the back end drops under a heavy load or trailer, steering and braking can quickly feel off. The Air Lift LoadLifter 5000 air springs add up to 5,000 lbs of load-leveling support to keep your vehicle sitting level and handling steady. Level suspension means better traction, proper headlight aim, and less strain on your factory springs and shocks. It’s the kind of upgrade that keeps your truck driving the way it should, even when it’s working hard.
Every haul is different, and this system lets you fine-tune your setup for each one. Inflate the bags anywhere between 5 and 100 psi to dial in firmness when towing or soften things up when unloaded. Each spring can be inflated independently to balance uneven weight from side-to-side loads. Manual inflation valves and air lines are included, giving you simple control without extra electronics unless you choose to add a compressor later.
These springs are built for the long haul with 2-ply, fabric-reinforced rubber that handles constant flexing under load. Air Lift’s exclusive upper and lower roll plates protect each bag and add strength where it’s needed most. The endcaps are made from high-strength Zytel nylon—lighter than steel but more corrosion resistant—so you don’t have to worry about rust or leaks shortening the life of your setup.
Heavy trailers or bed loads can make the ride harsh or unstable. The LoadLifter 5000 helps absorb road shock and minimize sway so your truck feels planted on rough highways or uneven work sites. By keeping the rear suspension level and supported, it reduces tire wear and helps maintain a smooth ride whether you’re hauling gear all week or towing on weekends.
Everything you need comes in the box—mounting brackets, hardware, air lines, and valves—so you can bolt it up with basic tools. Once installed, you can inflate the springs manually or add an optional Air Lift compressor system with in-cab or wireless controls for on-the-fly adjustments. It’s a straightforward way to get serious support without overcomplicating your setup.

We do recommend to at least keep the minimum of 5 PSI in the air bags to prevent a bouncy ride and damage to the air bags.

Not terribly hard to install, but would have been better include a three way tee to air up both sides at the same time

Thanks for including photos Brian! I'm glad these helper springs helped resolve the issues you were experiencing while towing your 5th wheel. Do you have any upcoming trips planned?
