Heavy trailers or bed loads can make the rear sag and the front lift, throwing off steering and braking. Firestone Ride-Rite air springs add up to 5,000 lbs of rear axle load-leveling capacity to keep your truck steady under weight. By spreading the load evenly across the suspension, they help maintain steering control, braking stability, correct headlight aim, and even tire wear when hauling or towing. The double-convoluted rubber construction cushions road shock so bumps don’t beat up your suspension or cargo.
Loads aren’t always the same, and that’s where the adjustable design shines. Each bag can be aired up or down between 5 and 100 psi to match what you’re carrying. Run just the minimum pressure for a soft unloaded ride, then add air when you hook up a trailer or load down the bed. Individual inflation valves let you fine-tune side-to-side balance for uneven loads so your truck stays level and handles predictably every time you hit the road.

These Ride-Rite springs are made to take real work. Each air spring uses four layers of reinforced rubber with a braided wire girdle that forms a double-convoluted shape for extra strength and burst protection. Corrosion-resistant metal end plates and a rolled crimp seal keep everything anchored tight and leak-free for consistent performance over years of use.
Installing rear axle air support doesn’t need to be complicated. The kit includes custom-fit brackets, hardware, air line tubing, and separate valves for manual inflation. The brackets mount between the frame and axle with minimal drilling on most setups, giving you clean alignment from the start. Add an optional compressor or gauge later if you want in-cab control—everything you need to get started leveling your load is in the box.
The construction material of the fittings may vary.

The air bags have held up well. I recently purchased the air command compressor kit from etrailer. It has a remote control, plus a phone app that allows you to control the air in the bags. The air bags are great, but spend the extra money and get the air compressor kit. It makes it so much easier.

Still a great product a year later. I have pulled heavier trailers across the country,used it for my 30ft travel trailer. Alls i need to do is adjust the pressure to my desired settings and the truck rides smoothly down the highway nice and level. Highly recommended product. Product is holding up well.

I still havent fixed the slow leak yet. Ive developed a rattle from the top half of the bag mount against the frame. Need to take that down and see what the issue is - nut might have loosened up. Weve got some pretty bad roads up here in the Northeast, so its no surprise. Other than that, theyre still working great. My idea on the T is a bad one, because that will introduce some severe body roll, as air pressure is forced from one side to the other depending on which way you turn. Will definitely decrease stability, so I wont be making that modification. Wish there was a way to hook this up to my existing Viair compressor. Suppose theres a way, just not an easy one.

Still goin. Pickup rides great even if I forget to lower the pressure after parking the trailer between trips.

It does sound like the air bags get a lot of use. While on the trips you do want to check the hardware and air pressure periodically. It is not normal for the air bags to leak air but due to changes in temperature you could lose a few pounds a month If you are losing quite a bit of air pressure it is likely that you have a leak with an air hose, air bag, or valve. The easiest way to see if you have a leak is to mix a spray bottle with soap and water, then spray the soapy water mix on all of the air bag components with the air bags filled up. If you see any bubbles that is a leak, and you will need replace or fix the leaking component. With regard to the truck riding 0.5 inches on one side, it is possible to correct it using a dual path system like part # AL25856. This would allow you to air up each side independently which could level out the truck evenly.

My nausea from the bouncing concrete roads is a lot less of an issue. I still need to air up the bag on the left side every week or two. I cant find any leaks in the hoses. It still rides 14 to 12 higher on the passenger side even with the air out but it doesnt effect the ride any. I do notice a difference when I forget to pump them up. They work. Im glad I got them but I think next time I would get the upgraded pump version.

I have traded this truck since then, however they improved my ride and stance every time I pulled my trailer.
