Heavy loads can drop the rear of your truck, throwing off handling and headlight aim. The LoadLifter 5000 air springs provide up to 5,000 lbs of load-leveling support to keep your ride level under heavy cargo or trailer weight. By sharing the load across all four wheels, they cut down on rear-end sag and help maintain stable steering and braking, even with a full bed or tongue weight pressing down.
No two hauls are the same, and this system lets you set it up for each trip. You can fine-tune air pressure anywhere between 5 psi and 100 psi to match your load. Add air for maximum support when towing or carrying heavy equipment, then drop back to minimum pressure for a comfortable unloaded ride. Each spring can be inflated independently using the included manual valves, so you can level side-to-side when loads are uneven.
When factory springs handle all the weight alone, they wear faster and cause uneven tire wear. These Air Lift springs back up your factory suspension by spreading the weight evenly across both axles. That balance helps reduce sway, bottoming out, and poor headlight aim while improving braking response and tire contact with the road.
Air bags see a lot of stress from heat, moisture, and road debris, so construction matters. Each LoadLifter 5000 uses 2-ply, fabric-reinforced rubber air springs capped with high-strength Zytel nylon ends that resist rust and corrosion better than steel. Air Lift’s exclusive roll plates add extra protection and increase the effective load capacity of the springs, keeping your suspension upgrade working smoothly for years.
Installing serious load support doesn’t need to be complicated. This kit includes mounting brackets, hardware, manual inflation valves, and air lines—everything needed to get up and running. Valves typically mount on the bumper for easy access whenever you want to adjust pressure or check levels. A compressor system with in-cab gauges can be added later if you want automatic control.

I'm happy to hear Amy was able to help you out with this Mark and I'll let know you gave her a shout out! Once you get the chance to install these, let us know how everything goes.

Would love to know your thoughts on them once you're able to try them out with the travel trailer, too! Thanks for sharing the different things you've used them with. Sounds like they are just the ticket for your scenario :)

Things are working well so far. I tow and haul during the spring,summer and fall. The most air I put in the bags was 50 PSI. The air still holds pretty good towing.Time will tell if the bags hold up as the bags age.

Nice job running the Schrader valves through the license plate, that's how I'd do it! '

Glad to hear they are working well for you and they weren't too difficult for your mechanic to get installed, Matthew! Sounds like you have your Taco pretty tricked out! Are you doing an overlanding type thing?

The Air Lift is working GREAT a year later. We just hauled a Generac 705 miles up north and brought a load of big rocks back for a guy that wanted to build a waterfall for his coy fish and the Air lift system was able to handle the weight just fine and rode great. Every one comments about how smooth the truck rides. The Air Lift system has handled everything we have asked it it to and has been trouble free. These will go on every truck I won in the future.

Besides the time it took, I am glad you were able to get these installed and notice a difference right away! They look nice installed. Are you towing anything other than your dump trailer?
