This is a major reason why air spring systems also known as air helper bags have become so popular in recent years. So, what makes air spring suspension systems so great? Read on to see why these tire-like, load-carrying components are the savior for any over matched OEM suspension system — and nine reasons why they belong on your truck.
There is no better way to ensure your truck tows and hauls how it was designed to than by making the rear suspension sit level, courtesy of an air spring suspension system. In addition to retaining factory handling, braking and steering characteristics more on that in numbers 4 and 5 , air springs reduce the potential for leaf spring fatigue, in which factory leaf springs permanently sag due to being overloaded and over-extended for lengthy periods of time.
With the ability to independently control air pressure present in each spring, air springs allow you to compensate for those uneven or off-center loads.
In addition to keeping you off the bumpstops, air springs will save your factory suspension a lot of wear and tear. With a leveled rear suspension, more precise and sure-footed steering performance is brought back into the equation.

I keep reading about people adding air bags to their truck. Does this increase the cargo or hitch weight capacity? Make it ride better? Give the wife another gripe about the upgrades I want to do to the truck?
I've tried to research it but still don't understand exactly what they do, except I know the third answer in my house for sure. Thanks in advance!
Join iRV2. It may increase load capacity a small amount, maybe lbs each bag. It also will in theory increase weight capacity We had some good times. It won't increase your registered gvwr nor gawr I jest as it will keep the weight off your overload springs, but does little for what you can really carry They help level the truck and maybe give you a better ride.
They do NOT increase any cargo, hitch, tow or any other rating. If you "need" air bags, you probably do not have enough truck. The only purpose of air bags in the rear suspension is to raise the rear end of an overloaded tow vehicle so the headlights don't aim at the stars and blind oncoming drivers. Load the truck down with all the people, pets, tools, jacks, whatever will be in the truck when towing your new toy hauler.
Go to a truckstop that has a CAT scale and fill up with diesel. Then weigh the wet and loaded truck on the CAT scale. If you don't have the 5er hitch installed yet, then add pounds to your wet and loaded weight. Subtract that weight including weight of the 5er hitch from the GVWR of your truck to get the max payload available for hitch weight. Wet and loaded smaller 5er toy haulers will have a wet and loaded pin weight of about 17 to 20 percent of the GVWR of the trailer.
So to see how much trailer you can tow without being overloaded, divide your max payload available for hitch weight by 0. This is especially important given that not all roads are created equal. Driving on a smoothly paved road may require a different suspension level than a rocky dirt road. According to Strutmasters, air bag suspensions are expensive and come with a lot of maintenance.
Air suspension, or more properly pneumatic suspension, systems have been around for nearly a hundred years. I had a lot of questions about what air bags do and why I would even need them. You need to consider that many other systems on your truck—including braking and cooling—are rated for your specific manufacturer-rated capacity.
Exceeding these ratings is not safe. After a lot of research, I went with a load support system from Air Lift and I wish that I had invested in the system years ago. My system included the air bags and an onboard air compressor with wireless remote control so I can inflate and deflate the air springs with a touch a button.
Not being much of a mechanic, and reluctant to break my truck, I thought it best to have the system installed professionally by my local tire and repair shop, TireRama. I was incorrect. I think that even I could have done the job had I been so inclined.
