Firestone Coil-Rite Air Helper Springs - Rear Axle

Installed on my '08 Acura MDX, very tight fit, it would work perfectly if air didn't leak out of the connection at the bottom of the bag.
It was a very lengthy install process for me, about 6hrs due to a stuck rear strut bolt that required drilling out. Also, needed an additional person to re-install the coil while holding down the lower control arm and squeezing the coil back into position.
The air leak is easily identified where the air line connects into the bottom of the airbag. I've re-cut the airline multiple times to ensure a perfectly flat end of the tube, and re-connected it. Even had a mechanic check the system, but there's still a slow leak at the connection into the bag.
These airbags seem very sturdy, but this is starting to make me second guess the quality, it seems like that connection is a clear weak point/design flaw.1245015

Customer Service will reach out to you about the warranty.

Works great on my 2010 Honda Odyssey. Easy to install if you remove the main bolt of the suspension lower arm (that holds the spring). This is a much better approach than to squeeze the bag between the springs. On an Odyssey, you must first remove the yellow rubber stop bumpers at the top of the springs.
I've attached pictures to show the installed part, the air hose attachments, and a side shot to show the lift I can now achieve with only 24 pounds of air pressure in the bags.
Also, the customer service was outstanding. When I ordered these, Firestone was out of the part. As we waited just under 2 weeks for more to be manufactured, Lexus (not a car; the name of my customer service representative) kept in regular contact with me and was exceptionally courteous and helpful. If you have a minivan that rides low when loaded or towing, I highly recommend these and I am extremely pleased with etrailer. 210948

Its a year later and I still love the product!

I purchased the Firestone Air Helper Springs for a 2006 Acura MDX. I wanted some extra lift in order to pull a large pop-up camper (300 lb. tongue weight). I had the springs installed by a local mechanic (install time was approx. 2 hours). Product works great and gives the extra lift that I needed while trailering. I would recommend filling the air springs with a hand pump. With the small volume it is tricky to get just the right amount of air in the system. 46957

2009 Honda Odyssey

The product turned out great. It does the job of levelling out our Honda Odyssey quite well while pulling a boat. I'd like to make a recommendation. After the instructional step of drilling the hole in the bottom control arm, I wish there was something that was provided to protect the sharp edges of the hole that the airline runs through. It seems like a very vulnerable spot where the airlines could be severed. Someone needs to design a hole protector sleeve that sits straddled/sandwiched between the air bag and lower control arm that would protect the air lone travelling through. Just my thoughts, otherwise, this is a wonderful product!405526

Installation of the first side was pretty slow and frustrating. The second side went much better. Dealing with the coil springs is always difficult, and I had a hard time getting the coil spring seated properly. Also, determining where to to drill the hole for the airline is difficult. I ended up using a Dremel to get it in the correct spot. Anyways, the air springs seemed to do their job, and adding 20 psi of air raised the back about 1/2". My wife complained about some squeaking coming from the back. Probably from the coil spring not being seated properly. A week after the install, the Pilot was rear-ended and totaled so I can't give any long term advice.82892

I'm very happy with this product after installing it on my 2005 Honda Odyssey. The instructions for installation were easy to follow. The stability unloaded is noticable.
I put about 7 lbs of air pressure on each side. I haven't tried it yet loaded, but I believe it will perform as it should. Thanks again etrailer.com great customer service and fast delivery.825622

2008 Honda Odyssey

Excellent product. Fairly easy to install on my Odyssey 08. Lift well the end of the car with my popup trailer.1119192

I installed these on my 2006 Honda Odyssey to pull an 18ft (total length) popup camper. My van used to bounce pretty good through intersections and would occassionally bottom out on the big bumps. After putting these in, it rides nice and level, and hardly bounces at all, improving the ride for passengers and popup alike. One note, I had them installed at a local shop and he ran the airline so each stem comes out just in front of the rear wheels (through the bottom body panel) to avoid the exhause. 12359

Easy to install with the help of a friend. The bags inflate easily once installed. Toughest part of the installation was drilling the 1/2 inch hole on each side. Make sure you have some good drill bits!34355

I am mechanically inclined, but these were near impossible to DIY on my 2006 Honda Pilot. Paid a pro to install, both are leaking but I have not checked it out. Not very pleased at this point.148021

I am very happy with this kit. It fits perfect on my 03 honda pilot the instructions are detailed. the kit install quick and has everything you need to install (except tools). Great customer service!!34482

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.1543675

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.1739895

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.1749244

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 great1750387

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.1453030

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.1715669

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!1752655

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.1777598

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.1703501

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.1590887

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!1493236
