Heavy loads can make the rear of your vehicle sag, throwing off braking, steering, and headlight aim. This Air Lift 1000 Universal Air Spring Kit adds up to 1,000 lbs of load-leveling support inside your rear coil springs to keep things balanced. It helps maintain a level stance when hauling or towing so your handling feels consistent and safe mile after mile.

Every trip is different, and this setup lets you fine-tune support for the job. You can manually adjust air pressure between 5 and 35 psi if your spring pitch is greater than 1", or 5 to 50 psi if it’s less than 1". Inflate both springs evenly for balanced loads or separately with dual air lines to even out side-to-side weight. It’s an easy way to keep ride height right where you want it whether you’re towing, hauling, or running empty.

These durable polyurethane air springs fit neatly inside your existing coil springs to take the hit from bumps and rough pavement. The design helps cut down on sway, absorb road shock, and reduce tire wear and strain on your stock suspension. The result is a smoother, more stable ride when you’re carrying gear or pulling a trailer.
This kit comes ready to go with two air springs, two heat shields, tubing, Schrader valves, and hardware. Installation is straightforward—just position them inside your rear coil springs using basic tools. Once set up, you can add a compressor system (sold separately) later for on-the-fly pressure adjustments right from the driver’s seat.

Hello, everybody. This is Jeff at etrailer.com. Today, we're gonna take a look at the Air Lift 1000 universal air helper springs for your rear coil springs. Now, these will provide your vehicle with up to a thousand pounds of load-leveling support. It'll help reduce the strain on your rear suspension, and improves both safety and ride quality. They are designed to support your existing rear coil spring suspension when you're hauling or towing.
These do help keep your vehicle level when you're hauling heavy load. Helps improve your steering and braking performance. It'll even help maintain safe headlight aim. And it also keeps your tires from wearing unevenly. It does let you manually adjust the air pressure to get even load distribution and support that you need.
You can level your vehicle front to rear. And with the installation of dual air lines, you can inflate each spring independently for side to side leveling of any off-center loads. Now, the adjustable air pressure in these springs are 5 PSI to 50 PSI. These will improve overall stability and ride quality. Diminish any sway, help absorb road shock for a nice smooth ride.
Now, I want to zoom in and just show you as I squeeze these, they are constructed of a durable molded polyurethane. They do basically install inside your vehicle's rear coil spring suspension. Now, since this kit is a universal kit, you will need to make two important measurements. Basically, with the vehicle unloaded and at normal ride height, you'll measure the inside height of your coil spring, which will be from the upper spring seat to the lower spring seat. And then the next measurement is the inside diameter of the spring and its widest point.
Once you have both those measurements, you use the table that's on the product page of this product to pick your correct universal kit for your application. This kit here is designed to fit a maximum height measurement of 11 inches and a minimum inside diameter of five inches. Now, since the air spring cylinder will inflate, it is okay if the cylinder is slightly undersized compared to the size of the coil spring. And additionally, some kits include spacers like these right here, which will make up for any of the height differences. Now, this kit, as you can see everything laid out on the table includes the two air springs, the four half inch spacers, the two heat shields, the tubing, the hardware, Schrader valves, all for manual inflation. Now, you can add a compressor system with in-cab gauges to monitor and automatically adjust the air pressure. Those items we do sell separately on our website. Now, these parts are made in the USA. Again, the load-leveling capacity is up to a thousand pounds. Now, you do wanna remember, Air Lift 1000 Springs will not increase your vehicle's weight carrying capacity. So, you wanna make sure not to exceed the manufacturer's recommended weight limit. But that should do it for the review on the Air Lift 1000 universal air helper springs for your rear coil springs..

This product did everything I hoped it would, no more bounce and sway while towing. I would recommend these air bags to anyone towing a trailer.

Holy cow, so it’s been over a year, I have had no problems at all matter fact, I forgot the airbags were even on there, they’ve held air once I got them where I want them. I have not even touch them they work fantastic, like I said 10 years ago I used them on the wife’s car and I came back because it’s such a great product, kudos to airlift.

Another year and the bags are still working great. They are used every time we do a trip with our camper. No issues note: you will experience minor pressure decrease over time but nothing major.
