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.
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. 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.
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.
Air Spring Construction
Coil-Rite springs are constructed of durable, elastic polyurethane to ensure years of service. Single replacement springs (sold separately) are available for maintenance to an existing Coil-Rite kit.
Air Spring Installation
The Coil-Rite springs install inside your existing coil springs. The custom-fit springs attach to your vehicle's spring seats.

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.The instruction are not for independent rear suspension. They are for a straight axle. All you have to do is disconnect the sway bar links and remove the shocks and you can slide the bags into the coils. It’s not easy though. They do make a big difference in towing. I cut a piece of aluminum angle to make a bracket for the valves, and that makes it easy to access for pressure adjustments.
Air bags have worked well on our 2010 Sequoia for one full year. We also pit purchased the service kit, but we haven't had to use any of that yet.
Working great after a year but rarely used. Easy install at home.
We installed a set of airbags in Fall of 2020. We originally gave a five-star review. However, air leaking started in about a year. By Fall of 2022, the left airbag was diagnosed as leaking. We're having another set installed in a couple of weeks. So, because of the problem, I'm down to at least three star review on these airbags!
Great product, with moderate install. I had to drill out the lower pan of the coil spring in order for the hose not to be pinched. Other than that, it went smooth and has been working great for almost a year. I would highly recommend this product.

Fantastic product. Theyre on my 2011 Toyota Sequoia and still works like a charm. By increasing the suspension on my rear wheels, my stability has improved, trailer sway has been eliminated and my rear tires dont wear out on the insides. I just wish I bought these air bags years ago. Since installing 2 years ago, I have travelled approximately 5,000 km while towing with no issue. While towing I fill to 30 psi, and when not towing, I keep them just under 10 psi.
Great product, I have it on my 2003 Silverado to level the truck out while towing my 5th wheel. I only gave 4 stars because I think it should come with a "T" fitting so both bags could be filled at the same time with an equal amount of air.
Easy install on 2011 Sequoia. Jack up and support right side of vehicle, remove wheel. Deflate and plug bag then stuff into the middle coil of spring. Use soapy water if bag hangs on spring coils, I used sweat.
Make sure you run the air line through the top of the spring mount before unplugging the bag. As soon as you remove the plug, attach air line to bag. It's much more difficult to plug in the air line after bag is inflated.
Run air line to left side and repeat , about a 1 hour job. Firestone really should include a T fitting to run the bags together.
At 10psi Sequoia sits about 1/2" taller in the rear, I'll probably run them about 8psi unloaded. Will have to see how they perform and hold up under load, so far I'm impressed.
They followed up very well
Good company
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.
The Firestone airbags are very well made and has quality feel. It was not very warm in MN when I installed them so I needed to use lubrication and a heat gun to warm the airbags from a distance so the airbags would be pliable. My gladiator has a Decked drawer system and rear steel bumper installed which caused the rear to squat more than the front. After installing these airbags and learning that I was fluent in “FRENCH” the rear of the truck was raised and squatting issues addressed. The drive was improved as well, less body roll around curves.
I have purchased 3 sets of Coil-Right. The product is very good but the installation instructions were terrible. The first set (2023) I installed per video instructions and it failed. The puck that is placed at the top of the bladder fell of and caused a catastrophic failure. The bladder was punctured and was basically destroyed. The second set (2023) I installed per the video but I enlarged the hole in the puck to help is stay on top of the bladder It failed also. The third set (2024) installed per the new installation instructions which removed the bump stop at the top of the tower. So far they seem to be working better but I think eventually the puck will diappere because there is nothing to hold it inside the spring. Time will tell. This is the only product for my vehicle I can use. 2021 Toyota Sienne LE.
As most have indicated fitting the bags in the springs is the hardest part. one tip I found helpful was once the bag was partially in, force the bottom of the bag with the air tube into the center of the spring then slowly let the air go back into the bag. Once it had some air in it i was able to move it around and get into place. once installed at 20 psi it raised my back end two inched. from 35" to 37" It is now level with the front of the vehicle. my vehicle is a 2015 armada platinum. Yes it has the auto leveling system. But the system wasn't functional. I've used these before in a 2010 armada platinum and it worked out great
Great product. I must say that they were a little tough to install. A very tight fit. Fortunately for me I had the availability of a vacuum pump. With that I was able to evacuate all the air out of the bags which made them flatter, with that, it made it easier to slide them between the coil springs. I tow a small camper trailer, I usually run around 20 psi in the bags. This keeps my vehicle level and adds for a smooth ride. A great product.
I can only give this 3 stars because one of the bags only holds air for about 1-2 days. The other bag stays filled for months. When they are both filled it gives my Pathfinder about 1" of extra lift while towing our travel trailer. So, the trip to the campground is fine but then I have to find an air pump for the trip home or tow with it lower. If they would both stay filled I would give them a 5 star rating. I contacted etrailer support and was told that I had to contact Firestone for warranty support. I have emailed (can't find a phone number on their web site) them twice with no reply.
These things are awesome. Install was a bit tricky with actually getting them inside the spring. Defintely don’t attempt during the colder season as the material is NOT pliable. A bit of soapy water helps if the springs uncompressed still aren’t wide enough to easily work them in. They’ve held up great and provide a decent ride when the vehicle is loaded down. Minimal squat!
I'll preface with I am an average do it yourselfer. I tried I stalling them on my VW Atlas for almost 3 hours before I just quit. I had to have them professionally installed. The installers said it took two of their people trying to fit the air rites in each spring. After installation they have been fine. My vehicle drops a little when I hook up boat but not a problematic amount. They hold air for quite a while and have not made any noise while traveling. They work as should. Just be prepared to pay for an install in event you cannot get them in.
The bags seem too short for my 2011 Yukon. The bags increase the spring rate but don't provide any lift to level the truck out. The air hose also keeps coming out of the bottom of the bag, I'm not sure if that is also because they are too short. I've tried to keep the min 5psi in the bags when not towing but the hose just pops out and leaks the air out anyway. My best guess is the wrong part number is listed for my vehicle. Pretty disappointed overall.
They provide support for my Volkswagen Atlas 2022 when towing our travel trailer. Installation wasn't' too challenging other then pushing the bags into the springs. Once I flattened them out and rolled them into a hotdog bun shape with zip ties, went in easy. I also added 90 Degree elbows to avoid kinking the hose if too tight.
Installation was every bit as difficult as other reviews say. I removed the plastic covering the springs, used lubrication, and nearly gave up many times. But in the end, I got them both in place. The only problem I have had have been leaks in the hose caused by my placement. Both times I removed the punctured areas and replaced it with new hose.
As far as function, I have been very happy towing a 1900 lb trailer with my 2012 Toyota RAV4. The air help springs keep the tongue level high enough without sacrificing ride quality.
Overall, I am very happy. I wish they were easier to install!
This system require drilling on even though this item says no drilling is required, the 2021 and newer Toyota Sienna FWD models require drilling. This is direcred in the toyota minivan specific instructions. You have to download the specific instructions for the Sienna that are linked in the description of the item.

NOT GOOD!! After 1 year, system losing air, left airbag leaking. Tried contacting Firestone Dont waste your time, voice mail jail. eTrailer does not sell 1 replacement air bag! So, ended up buying a new set, to be installed next week.
