I bought a 2018 Ram 1500 last summer. We use it to tow a 7,000 pound trailer. When towing a trailer, the truck bed is usually filled with tools, firewood, extra propane tanks, a generator, etc. Also, my family has 5 people plus a dog. I like our 1/2 ton ram, but its weak point is the rear coil springs. They offer a fantastic unencumbered ride to work. But they are not designed for serious work. Air Lift 1000 bags solve this problem. They reinforce the rear coil springs to prevent sagging and sagging. This makes driving safer and more comfortable (loaded). I pump 5-10 pounds of bag air when the truck is unloaded, which doesn't affect my driving performance. To be clear, airbags do NOT carry weight. To do this, you need the right weight distribution. But even with the WD clutch properly adjusted, my truck still sagged in the back. These bags are a life saver! They are inexpensive and relatively easy (if a little time consuming) to install. Air Lift's customer service is amazing. They really stand behind their product. I have used and abused these bags for the past year. During the winter I developed a slow leak somewhere in the system. I emailed Air Lift because they have a lifetime warranty. More or less no problems and Air Lift sent me a brand new set. What's even nicer is that they sent me new improved 1000HD bags. I offered to pay the price difference but they didn't take my money. The new bags are even better. They are stiffer for better leveling ability and have a better ability to connect air ducts to pockets. It was difficult to remove the old bags! But that has to do with the quality of the product. I couldn't believe how thick and strong the red 1000 bags were! Black 1000HD bags are even thicker. I hope I never have to take these bags off lol. End up buying these bags (or 1000HD bags). You will not regret it. This is a cheap and easy option that works well and is backed by an excellent warranty and customer service.
