For safety and stability, air springs are the perfect partner for your rear suspension when you are hauling heavy loads. Springs fit inside existing coil springs to help level your vehicle, improve braking and handling, and reduce tire wear.

Note: The construction material of the fittings may vary.
Hauling heavy loads or towing a heavy trailer can make the rear of your vehicle sag and the front end rise. This puts more strain on your rear axle and reduces contact between your front tires and the road, causing problems with braking, steering control, and traction. By adding air springs to your rear suspension, you can help to level your vehicle for more effective braking and handling under heavy loading or when you encounter adverse road conditions. The air springs also help to level your headlight beams and reduce wear on your tires. Firestone Coil-Rite springs fit inside your existing rear coil springs to maximize the effectiveness of your suspension system. The added cushion provided by the air springs allows your vehicle to better handle a heavy load or trailer.
Adjustable Air Pressure
The air pressure in your Coil-Rite springs can be adjusted manually, side to side, to compensate for off-center loads. A centered load improves the stability of your vehicle by reducing body roll. The air springs will also help to absorb road shock and soften contact between your axle and frame. This prevents bottoming out, thus improving ride comfort. Route the air line tubing for the springs to your vehicle's bumper to provide easy access to the manual inflation valves.
Coil-Rite springs are constructed of durable, elastic polyurethane to ensure years of service.
The Coil-Rite springs install inside your existing coil springs. The custom-fit springs attach to your vehicle's spring seats - no drilling required.

After installation we are towing on the level and enjoying the ride. In an effort to maintain the minimum air pressure to each Coil-Rite Helper at all times, we installed individual air supplies to each Helper. We used our onboard Horn-Blaster air compressor to supply two air pressure regulators allowing us to easily change air pressure to each individual helper as desired. Each regulator employs a check-valve to maintain pressure to the Helpers in case of a compressor failure. We have marked each pressure gauge to the minimum pressure and another mark for our desired towing pressure.
Installed on my 2020 Ram 1500 4x4 ecodiesel. Took about 1 hour. Jacked up rear of vehicle to let coil spread out a little. Bags went in easy. Air lines were simple to run. Bought the union T-valve so I could air the bags up at same time and to make sure equal PSI goes to each bag.

They still working great. Only minor issue is the line that threads onto bags do come lose and cause air leakage. Recommend locktite to solve the issue.
First and second set I tested before fitting them and they both leaked from the pvc pipes to the metal fittings. etrailer replaced the first set. When the second set leaked I cut the connection off and heated the pvc and joined it to the metal fitting, no leaks and works well.
This is the best addition I've ever made to a tow vehicle! I have a 2020 Ram eco-diesel and I pull a 2016 Rockwood 25' travel trailer. Combined weight is about 11,000 lbs. These air bags help the truck handle much more confidently. My wife noticed a difference on our last trip (2200 miles round trip). The half ton Ram does a great job, the bags eliminate the little bit of squat. The level combination makes towing a breeze. The only hang up is installation. They do not squeeze between the spring coils. I installed mine at home but it wasn't easy.
Absolutely love these. Made towing my Rv a breeze. Highly recommend them.
Really helped with the ride quality when towing.I installed these in my Ram in my driveway with the help of some jackstands.
Install was straight forward. However, The connectors are fragile and must be secured with great care. They are easily fractured and prone to leaks. Impossible to fix without wheel removal and spring removal. Once connected securely, it works well.
Install was not easy, would recommend just removing the coil spring vs struggling trying to shove the bag between coils. I struggled for about half a day before I was finally able to get both sides in. After installation, one side was leaking from the crimped connection between the air line and the brass fitting on the air bag side. This is not something that can be repaired. etrailer wouldn't help because of the time since my order (took me outside of their 60 day return period to install the bags) although reading their policies, they only allow returns of unissued items anyway so not sure if they would have helped anyway. Trying to work directly with Firestone to get a new air line so we'll see what happens.
Overall almost great! When towing my 26' RV you can tell/feel the difference. One bag has a very small leak. I have taken the lines off twice and re-attached them. One bag never leaks. I would still recommend them.
Easy to install and really helped to keep truck level.
GREAT CUMSTOMER SERVICE FAST DELIVERY!
Superior to previous brand of air bags installed on older Ram. Firestones are less expensive, retain pressure setting and are easier to install.
easy install
Exactly what I need, truck would settle with camper hitched up, now it doesn't. Simple easy fix
Overall great product it has performed exactly as I needed. However it is not an easy install at all. I am a very experienced mechanic and I ended up taking it to a garage that had a lift. They had to drop the rear axle down to get air bags in springs. That cost me another $200. The mechanics exact comment was " you would have never got these in without a lift". I would buy again but I would not attempt without a lift.
Works great towing my trailer. A little rougher ride without the trailer, but knew that at the start
Easy to install it worked great
Have not installed yet but am excited toget er done
Worked great, would recommend this product, etrailer was very helpful finding me the parts I needed
They do the job.

Working Good! Although the air fitting on the starboard Coil-Rite came loose last month. We tightened it down as instructed and then generously coated the fitting with gasket maker. I doubt that will back out again. These Firestone Coil-Rite Helper Springs greatly improved our towing experience. Our regulator system allowed us to easily adjust the pressure to the each time we unhitched, which allows the truck headlights to be properly adjusted.
