Heavy loads in the back can make your rear end sag, throw off your steering, and mess with headlight aim. The Air Lift 1000 air helper springs add up to 1,000 lbs of load-leveling support inside your rear coil springs. With that extra help, your vehicle stays level when hauling or towing, improving handling and braking performance while reducing tire wear and stress on the factory suspension.
Not every load is the same, and these air springs let you tune the setup to match. You can manually inflate each spring anywhere between 5 psi and 35 psi for the perfect balance of comfort and support. Add more air to handle heavy gear or towing, then drop it back down for everyday driving. With dual air lines installed, you can even adjust each spring independently to level off-center loads.
Bumps, sway, and bouncing can make towing or hauling stressful. These molded polyurethane air springs absorb road shock and minimize sway so your ride feels more planted and controlled. By supporting the coil springs directly, they help keep your vehicle steady through turns, over rough roads, and in shifting crosswinds.
Installing real suspension support doesn’t have to be complicated. The Air Lift 1000 kit fits right inside your existing rear coils using basic tools. It comes complete with two air springs, tubing, Schrader valves for manual inflation, heat shields, and hardware—everything you need for a clean install. Add a compressor system later if you want in-cab pressure control without leaving your seat.

I forget they are there! Its only when towing trailers or putting something heavy in the bed of the truck, I am reminded that its a very practical upgrade to the trucks suspension. When checking tire pressures I check the airsprings pressure. Pressure s are minimal.

Been working out great. Have used these bags to offset loads of wood, four wheeler, towing a skid steer and towing a mini excavator. Great bang for the buck. Add air when you need. it down to 5 psi for a factory ride. Also, I installed these without taking the fender liners out. Only had to remove the right rear tire.

After having this product for a year, I can honestly say that I will never be without it! With the addition of this simple inexpensive product, other than just the looks I have noticed that my tire wear has dramatically improved! you know how cheap tires are... In the last year I have put about 40k miles on the truck. Im in the Agriculture business and see a lot of dirt roads and drive out into fields daily.I check the system air pressure any time I notice a change in my tire pressure. I havent seen any leaks and that was my main concern.Overall, I am extremely pleased with this product and believe it was worth every penny.Bottom line, if you are reading this review and are thinking about purchasing this product DO IT!

Still pleased with the product. Towing my camper is so much safer and easier now that the truck is level.
