Firestone Air Bags

They will not increase your Gross Vehicle Weight Rating (GVWR). They will help level out your vehicle, prevent the rear from sagging and provide for a safer driving condition, but will not increase the towing capacity. No aftermarket overload or helper springs can change the rating that is set by your truck's manufacturer.

In the past, most of the air spring kits required drilling of the frame. Over the last few years Firestone has replaced many of these kits will new 'no drill' kits that do not require you to drill holes in your frame. There are a few kits remaining that do require drilling. You can download the instructions for each kit on our website and see exactly what is required for the installation.

Air springs do not replace your leaf springs. They work with your trucks leaf springs to provide extra support, but do not replace them.

The air pressure in the lines and spring will equalize. Ideally, they should be near similar lengths, but having one side longer than the other will not cause any problems.

Firestone air bags are designed to prevent your truck from squatting when a heavy load is placed on your suspension. They will bring it back up to stock ride height, but cannot raise and lower the suspension below or above stock ride height.

Air springs are made from rubber so how long they will last will depend on a many factors, including heat, road salt, how hard you are using your air bags, etc. Firestone has some of the highest quality components on the market and they should last for years. Individual replacement air springs are available if one is damaged or needs to be replaced.

The fittings are push-to-connect fittings. You simply push the air line toward the body of the fitting, this will also force the small collar of the air fitting toward the fitting. Hold the collar against the fitting and pull the airline out after the collar releases the air line.

On-board air compressors are not required to inflate the air springs. It is a nice option to have air at your fingertips and not have to worry about finding a gas station that has a working air compressor. All the kits come with 2 inflation valves, one for each air spring. You can inflate and deflate them the same as you would your tires.

Yes, and it is very common. Firestone part 3025 is the fitting that will work with all their air springs kits. Adding this fitting will remove the ability to level side-to-side but many of our customers find it easier to inflate both at the same time and not worry about how much is in each individual air spring.

This is really a personal preference and whatever works best for you. In our shop, we typically install them where they are out of sight. Common locations are near the bottom of the rear bumper, next to the rear license plate, or behind the gas tank flap. As long as they are not near anything really hot or moving parts that will damage them, you can put them wherever you prefer.

This will depend on the year and model of your vehicle. Most of the kits will work with a Fifth wheel hitch or Gooseneck hitches but it is always best to download the instructions on our website for your specific kit and see where the kit mounts and if it will interfere with your setup. Over the past few years, Firestone has developed a lot of kits that mount on the axle to prevent them from interfering with your hitch.
