Maybe excellent after I try to fix it. Seems the driver side wont hold air too long. I just need it when I pull my Casita camper with my KIA Sedona and I just add air before I start out. Not too annoying really. Fixing it may be a little more difficult then living with it. But I think it was a good idea to buy and install. 627708

The vast majority of the time, leaks will occur where the tubing enters the spring. If the tubing is not cut at a perfect 90° angle, its going to leak. You can test this by pressuring up the system and painting a solution of dishwashing liquid and water at the point where the tubing enters the fitting. If theres bubbles, theres your leak.

The instruction video showed exactly how to install these. Just disconnected rear lower suspension arms and drilled holes for the air lines. Swapped in the top plates for the air bags and put everything back together. They work great. We top them off every couple weeks, but really only necessary to top them off when we are going on trip or towing something. Hitch doesn’t scrape any more and body roll is reduced. Great investment. Highly recommend. 667173

I have a 2003 Acura MDX with 197k miles on it. I have used it for towing a 6x12 trailer for 3 quads. I have also towed many loads of dirt, mulch you name it. The rear sags allot and I just bought a 19' boat. I found this kit on etrailer and ordered it. The box came and it said it was for a Honda Odyssey. I double checked online with various sites and confirmed that all Acura MDX, Honda Pilot, Honda Odyssey, & Honda Ridgeline all have the same coil spring suspension with bumper stops inside the coil. I found a great forum which included pics of someone else that installed similar kit. I used those as references to install mine. Here are the steps to install which took about 2 hours: 1) Jackup car, and suppored with good jack stands 2) Removed tires 3) Using a 7/8" hole saw and made a hole in the middle of the lower control arm. 4) Filed the burrs 5) Installed a 7/8" grommet (not included in kit, I got this a local ACE hardware store) 6) Removed bolt from lower control arm knuckle to lower the arm. 7) The bolt for the bumper stop is not accessible, so I used a hand saw and cut about 2" of the rubber stop out. 8) Compressed the air bag and installed the plug (supplied) to keep it compressed, inserted the airbag thru the coil. 9) I deviated from the instructions which says to use the included plate at the top of the airbag which requires removing the bumperstop. Instead I placed this at the bottom of the airbag, which nicely has a grove in the middle which allows the connection for the airtube to sit in and keep it protected. 10) I routed the airline thru the factory openings in the lower control arm & rear end and up thru the trailer harness opening into the rear compartment in the trunk where the head rests go for the third row. 11) Reattached the lower control arm 12) Install tires 13) Lowered car 14) Inflated the bags to 15 psi which returned the truck to just a little above the stock height. I must say this is exactly what I was looking for. I towed the boat this weekend and didn't sag at all, the ride was much smoother then ever. Even with nothing attached to the truck, the ride is much better. My opinion is that this should be installed for anyone that uses the third row seat, or tows anything at all Acura MDX, Honda Pilot, Honda Odyssey, & Honda Ridgeline as it eliminates the typical rear sag! 146221

Installed easily on my 2016 Sedona. I am pulling a pop up camper and this helped keep it level without adding stiffness to the van suspension. I only wish the tube didn't hang down below the suspension, 616519

Love the product! Holds my Sedona level, even with all the kids plus a load in the rear. Evens out the ride driving over bumps. Great for towing a trailer. Only down side was installation. I had the product installed by the Kia dealer as I figured it would be easy for them; it took the professionals 4 hrs to install. Outside of the cost for installation, great value for the money. Highly recommend! 514351

Most challenging to install. Not snap fit. Removal of several components and careful routing of delicate air line also had to purchase grommets for holes where chaffing of air line would occur. Don't expect longevity. Suggest development of a single support spring assembly to be better engineered and increase longevity, reliability, and ride stabilization as well as load capacity. Rusted parts don't disassemble with out heat and air tools. New bolts washers and nuts should be included. Thank you 265078

Have not installed it yet but I will follow up when it is installed. Great ordering experience and all was as described on website. 141733

Kit has made the ride in my Honda Odyssey overall better. Also keeps the back end from sagging to far when I've got the trailer on. Quality parts (stainless steel valves and valve caps) easy instructions and it fits perfect. Only drawback was that I had to have my mechanic install it, but after talking with him he said that it would have been a challenge without a lift. 90923

I received my order and installed the Air Helper Springs the next day. I had the opportunity to fully test them yesterday. They were not difficult to install and the instructions were easy to follow. I do wish there had been a video for my particular vehicle since I’m not exactly sure my routing of the air line around the exhaust the best location. Time will tell. After hooking up my trailer I adjusted the air, best I could, since all my tire gauges start at 10 lbs and go up from there. I did get the rear of the Pathfinder as level as I could. A recommendation from etrailer on a good digital or analog gauge would have also been helpful. I did pick up a digital gauge today, works great. Thanks etrailer for a great products, instructions and your follow up email that answered my questions, 513109

Excellent! I use it when I tow my equipment trailer and I haven’t had “any” problems. I did alter the hose configuration to a single point of air input instead of a valve for each bag. I know their reasoning but single input works better for me.

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. 449007

Review from a similar Firestone Coil-Rite in Vehicle Suspension

Installation: 2007 Toyota Rav4. The installation instructions were perfectly fine. Installation is not a complicated process; it's just a struggle to get the air bag inside the coil and into its proper shape. Everything else is easy. Also, the instructions clearly stated how to remove the air hose from the air valve. Although not provided in the instructions, I removed the rear wheels for the air bag installation. While that took some weight off the coil's extension, the trade-off was easier access to the coil from the side rather than from underneath...and I did get the air bag inside the coils fine. In installing the air bags one bit of advice is consider using more fingers than tools. Once I put the blunt-ended tools down and worked it into place with my hands the install went much better. Once the air bag is inside the coil and the air plug is removed, the coil doesn't just pop into place/shape. It still needs to be worked in a spinning motion and using the soapy water from the sprayer that you'll need to check for leaks will come in very handy doing that. I tow a 1,000 pound covered trailer and have recently purchased a motorcycle hitch carrier to haul my dual-sport motorcycle. I always wanted this air bag set up for my towing, but it was the carrier that got me to pull the trigger on the Coil-Rite. Using the top of my rear wheel well as a point of measurement, the stock height was 32.75". Putting 525 pounds on the hitch receiver (motorcycle hitch carrier and motorcycle) the height dropped to 30.25" (-2.50" from stock). Pumping up the Air Bags brought the height up to 31.50" (+1.25" above the ladened height but still -1.25" below the unladened height). The specs on this product state that the Firestone Coil-Rite's load leveling capability ranges from "at least 500 pounds (at most 1,000 pound)." I was expecting the Coil-Right to level my vehicle with the 521 pound receiver tongue payload and it falls short 1.25" (or only half of the total ladened reduction in height). I'm giving the product a good rating as it was fairly inexpensive and something I could install myself...and does, in fact, help my leveling for towing. However, the spec says it should have leveled at 500 pounds and it didn't. 242614

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. 339214

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.

Okay, first of all. I have had this type of air spring helper bag before on several vehicles so I'm fairly familiar with how they are setup and work. Ordered this kit, good pricing, fairly fast ship..... And then the fun began. I did watch a video on the install. Looked pretty straight forward but with these latest polyurethane bags it looked like it would be a challenge to just "push" these through the springs AND get your hands in there to connect them. Oh, well I gave it a shot and sure enough one of the brass L shaped fittings for the bag just snapped off in my hand! Etrailer did address this and sent me new lines. And I'll be honest here.... threw everything back in the box and let it set for another month. Okay, let's do it again, MY WAY, this time. I dropped the rear coils completely this time, easily fed in the bags with the lines PREATTACHED, put the coils back in place and finished up the rest of the install. It's up to you....but I think just dropping the coils completely takes less time and you'll end up with a neater install. Oh, and here's the best part....these things are awesome on these long wheelbase Hyundai Santa Fe's. These SUVs don't have enough springing in the back to begin with. If you pull a trailer or hall a lot of tools, etc., in the back, trust me, you will see "extra" tire wear because that rear suspension will be sitting on the snubbers a great deal of the time. By going from around 10 to 30 psi I have a great deal of control over both ride height and improved stability in tow and heavy haul situations. I would recommend them, just take your time on the install..... 287475

Well, they still work well, however they dont hold there pressure for more than a couple of weeks. Always checking them...adding air every few weeks

I installed Firestone Coil-Rite Air Helper Springs and they work great. With minimum air pressure they improved the unloaded ride and driveability. Loaded the van for vacation, added air pressure to bring the ride height back to the normal ride level and the van drove and handled better than when it was new. Followed your on-line installation video and installation was a breeze. The installation instructions with the kit were poor and incomplete. . 139788

Review from a similar Firestone Coil-Rite in Vehicle Suspension

I must say the product was sold a great price, and delivered quickly. It installed easily following the directions and performed as expected. It handled the extra load on the 2012 Sante Fe and kept the ride smooth and level on our 1,200 mile rides. I do question the installation instruction as to the length of the stub tube under the elbow (at the top of the air bag). Installed it appeared the elbow was bent over at a very sharp angle and I fear a kink developing in the tube (though there is no problem to date and perhaps the little extra length prevents the kinking ?). They have been installed around 5 months now and have around 8,ooo miles on them. I have delt with e trailer before and will again....HIGHLY recommended 78713

Firestone prefers to handle warranty claims directly, so please give them a call. Remember that these bags do have a minimum air pressure. Firestone specs them at an operating range of 5-35PSI. If they drop below 5PSI there is risk that the bags will not hold their shape and pressure and be prone to damage because they are inside of a moving coil spring.

Made another trip to Florida since installed..LOADED..... and the airbags performed very well. Level vehicle and no real noticeable harshness in the ride. Im a happy guy.We load the car, put kayaks on the roof and put about 350 lbs in a receiver hitch style carrier and the car is level and rides nice. I have nothing negative to say. Oh, I run 45 PSI loaded like this and it works great.

It was tougher than the instruction stated. At 70 yrs. old I don't have the strength to get them through the coil. Problem solved, dropped the lower "A" arm and removed the coil spring, in it went.

Review from a similar Firestone Coil-Rite in Vehicle Suspension

Just installed the Firestone air bag system in my 2017 4Runner. After installing a 250lb aftermarket bumper the sag to the springs was just too much, I also tow a watercraft trailer so that would squash the springs even more, the simple solution is the Firestone air bag system. Install was easy. With my spare permamently out of the undercarriage I just used two existing holes to mount the valves. I think for what you get the price is a bit much, but you can look at it like the air bags will provide a service for hopefully years to come, so that is worth the price. 458968

Bought them for my Jeep to help with stabilizing the rear end when towing. They do the job for a little while (a day). Then they LEAK! Sent factory photos of leakage with soapy water spray bubbling from metal neck. Got a new one - SAME PROBLEM. Just sold the Jeep, but took out the airbags first. It was the only problem my Jeep had. Didn't want to have the airbags involved in the sale. Poor quality, not made to prevent failures. Difficult to prove defect to factory. Would not recommend this product. One would be better off getting another brand consisting of large, dense rubber cushion. No air to leak. 417990

I purchased this product on the recommendation of a service writer from my local VW dealership. I carry a lot of tools and equipment in me Jetta Sportwagen for work. Shipping was super quick and follow up was excellent. I just installed the air bags yesterday with a friend. Very easy to install. One helpful suggestion, after the first attempt to stuff the deflated air bags in the spring we found it too flat and hard to get in. I suggested squeezing the top end round like an eggroll and putting a cable tie around it to hold it and then getting the remaining air out. It goes it much easier and no need to remove the bottom shock mount. Huge difference on the ride home! Ride height back to level with 350 lbs of equipment in the back. I highly recommend this product. 231481

A full year later and not a single problem. I havent had to add air since I set the bags up. About 11k miles of mostly city driving.

I'm very happy with my Firestone Coil-Rite kit for my '06 Sienna. I added a "Tee" to join the bags together and routed the schrader valve to exit inside my fuel fill door. It was a little extra work, but well worth it as it's out of the weather and sight, and I don't have to scrabble around on the ground in the slop to check / adjust the pressure. I run 15 -17 lbs when I'm not hauling a load and that seems to help with body roll, and up to 25-28 psi fully loaded. The kit does the job it was intended for, and hasn't leaked a snif of air since I installed it a year ago. Three thumbs up! 350292

After one year of use I can say that this product performs very well. The installation video for my vehicle was very helpful. I did however find that warming the coil bag up in the oven, tie raping it into a roll and inserting from the bottom was easier than inserting through the springs. Also I would recommend that the Tee for the air lines be included in the kit. It was the only thing missing and I can not imagine an installation with out it. 439085

I installed the Firestone Coil-Rite helper springs on my 2006 Nissan Armada. The install went great, all done in about 30 minutes. My Armada used to sag 3 inches when my travel trailer (5,000 lbs) and 500 lb tongue weight before these were installed. Now with them installed it only sags 1inch and ride so much better. I did this vs a weight distribution hitch as my Travel Travel wasn't really heavy. I just drove it with 32 PSI from Atlanta to Orlando and back.. worked great no issues so far. 513441

Review from a similar Firestone Coil-Rite in Vehicle Suspension

Excellent product. Installed on a 2012 2x4 Nissan Pathfinder to stiffen rear end. We often load the vehicle with gear and a utility trailer and found it tends to squat a bit; the air bags solved that problem. Easy to install, but the instructions included with the units are incomplete as they omit inserting the support plates. However, the installation video on the etrailer website covers this and should be viewed. I was able to do the installation with the vehicle on the ground and without removing the wheels. I dropped the spare tire and jacked up one side at a time just to where the tire was almost off the ground, placed jack stands and worked from under the car. You really need to be able to put a lot of pressure on the deflated units to get them inside the coil springs. I found the best tool for doing this is a ball peen hammer; using the handle to push against the bags and the head for a good grip that allows pushing real hard without damage to your hand. 316982

Review from a similar Firestone Coil-Rite in Vehicle Suspension

This is our second Ford Flex and the second one we've added these Firestone Coil-Rite rear spring assists. In the year since we had them installed we've moved using an 18' twin axle enclosed trailer packed to capacity, taken several modest trips (approx 1000 miles) and driven the Flex as a passenger car. I've had the air pressure set as high as 30 PSI when towing, and as low as 5 PSI for daily driving. They work great. They add just about 1" lift at the hitch receiver with pressure of 30 PSI and the car unloaded. With the trailer attached this works out to be just about level. When packed for a trip, I've used 10 PSI to 15 PSI depending upon what we've loaded into the back. Again, it keeps the back end from squatting and keeps the headlights aimed properly. I installed the kit using separate air valves for each side this time. I like this better than using a common filler. It seems to add a bit of "roll resistance" having each one filled separately. Our first Flex I used a common filler valve and didn't get this benefit. My only word of caution is to be careful when filling the air springs. It doesn't take a lot of air to get to the desired pressure so be careful not to over-inflate. Also, if you have a tire gauge with a "bleed down" valve, it works better than one without. Just as with filling, it doesn't take much depletion of air to drop the pressure significantly. A gauge with a bleeder allows you to draw off just a little air at a time. 334563

I installed these on my 2014 Cadillac Escalade ESV. I pull a 29’ enclosed snowmobile trailer with a 7,000# rating. These help tremendously with sag and sway and make life safer and easier when trailering, particularly when dealing with a crosswind. Installation is a little bit of a knuckle-buster but can be done easily at home. 570838

I installed these on my 2014 Nissan Pathfinder, which despite being rated to tow 5,000lbs, really struggled under the tongue weight of my boat trailer. These airbags really made a difference when towing and only when speeding over speedbumps do I notice them in normal conditions. My only complaint is that the valve stem points down, which once hooked to the hose, sticks down nearly two inches and was routinely getting ripped off in the snow. I finally gave up the hose and just rolled under the car to increase the pressure (which I've only done once). The kit should really come with a 90* connector, but otherwise it works great. 497497

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. 419436

Review from a similar Firestone Coil-Rite in Vehicle Suspension

Overall, etrailer service and the instructional video were excellent, installation was easier than I thought, and performance has been very good. I installed these on my '07 RAV4. Quick delivery, excellent follow-up by etrailer. Having read other reviews, I was a bit apprehensive about the installation. It went much quicker and easier than I anticipated. No bruised knuckles, a few grunts, no cuss words. The video is very good and helped a lot. I jacked the car up until the wheels were off the ground, which gave a reasonable amount of room between the spring coils. The red plug popped out a few times but you could still squeeze the bag with one hand through the spring and then put the plug back in, which gave some laxity in the bag to help manipulate it. The exhaust was in the way on the right a bit but not really a big deal. I opted to install the tee fitting and routed the valve stem into the left rear, as per the video. I chose to install it in the "dimple" below the 12v plug present in my car. Be careful, though: if you put the stem in the exact center of the dimple, many tire fillers won't fit into the dimple, so install it offset to the bottom. Also, I routed the tubing through the rubber grommet (maybe 1' dia) in that space on the bottom towards the vehicle front. The bags seem pretty easy to inflate with an inexpensive 12v compressor. As for performance, they seem to do very well, cutting down some of the bounce when towing our pop-up trailer. 386041

Thanks for the follow-up: reviews at this point are much more useful than ones immediately after purchase. They’re working very well and we’re very happy with them. They do tend to squeak a bit when low on pressure and they do seem to leak a tiny amount over time but neither are a big deal. I would definitely get them again.

Thanks to all of the folks who shared their observations on the installation of Firestone Air Helper Springs on Toyota RAV4s. Some of their suggestions made my life much easier. The Firestone instructions, as others observed, were pretty generic and were probably not written by a person who actually installed them on a RAV4. Here are a few things that I found useful: I found that the easiest way to cram the air bags into the coil springs was to flatten them like a pancake with the top and bottom surfaces collapsed onto each other and lash them in this state with a zip tie. Compressed this way you can push them thru the gap in the coil spring in the correct orientation so that when you release the zip tie they expand into the coil spring correctly. It helps to push them thru an opening just below the center of the coil spring so that the air bag ends up slightly below center touching the bottom plastic protective disk. It is really difficult to move the air bags up or down once they expand into the coil spring. I attached the air hose after the bag was in place. You can use a heat gun to warm the air hose enough to bend it so that it exits the lower control arm, turns 90 degrees, and runs along the back of the control arm without hanging down. As others noted the exhaust system presents special problems on the right side. I ended up routing the air line toward the brake and up to the upper control arm to stay away from the exhaust pipe. It's not clear what the best strategy is for routing the air lines. They seem pretty tough, but will likely be rubbing on something given all of the movement in the suspension. I'd suggest not cutting the air line and starting with the right side, which for me needed more air line length to keep away from the exhaust system. That way you will have enough air line to finish the right side and you can use the remainder on the left side, which will need less. I cut the line in half to begin with and barely had enough for the right side. All of the bits seem to be of high quality. The quick connect air fittings seem to seal well and grab tenaciously so you will have a very hard time removing them once you install them. Like a Chinese puzzle on steroids. Our trailer has around 440lb tongue weight and these have brought us back to level with a few psi to spare. We'll see how it goes over the road. Thanks to everyone who contributed ideas and suggestions. 161229

Air helper springs were a huge help, leveled the back I'd my Rav 4 making a huge difference when towing my travel trailer. Instillation videos were very helpful, I did not have to contact etrailer for help. Shipping was fast all parts fit as expected. 540431

As a former mechanic, this was a tough install. It was a struggle to get the air bags through the springs and there was not enough room to remove the 3" piece of tubing so I installed the bag with the full length of tubing already in place. I was hoping to gain about a 2" lift, but it only raises the vehicle about 3/4 of an inch. The bags do make a noticeable difference in handling and the hitch is not so close to the ground while hauling a trailer. 103341

Good product with a relative ease of installation with the right tools. Only improvement would be to add a Tee in to the air line so there is only one needle valve for adding air in to the system. 249275

The product came very soon after I ordered it and is just as what is pictured. While there are no instructions in the kit - I am a capable mechanic and do not need any. It was tough getting the bags into the springs of a 2013 Pathfinder. I relaxed the suspension as best I could, but the spaces in the coils are not large. It helped to insert the bags from the middle of each spring. The air lines are a combination of schrader valves both conventional and friction fit - take care to trim the friction fit square. I used a sharp knife. I had to fabricate a mount for the exterior valves and used a piece of 1/8 sheet aluminum. I noted the difficulty of routing the air lines away from the hot exhaust and over extension and flexion. On my vehicle the air line must extend from the bottom of the spring and this will, unfortunately increase the risk that the line will foul on a road hazard. Spend a few moments under your vehicle and route a path for the air lines before starting the install. Overall these bags seem to be a rugged option for a suspension boost. I will add to the review as time goes on if necessary. 295316

So far this has been every thing it was advertised to be. Install took a couple hours give or take I didn't really time it. The install went well, no busted knuckles or any thing! I forgot to order the "T" fitting so I'll have to go back and take care of that. So when you order get the "T" to avoid my error. Etrailer has been great. Deliver was timely when I made the order the Coil-Rite set I needed was on back order but as estimated by etrailer it arrived within two weeks, so no big deal there. I installed the Coil-Rite on my 2014 Toyota RAV4 to help level the body out when towing our ATV trailer. I haven't had a trailer hooked up to it yet but looking forward to it. I'm pushing the max towing capacity of the RAV so I really want to keep the breaking as solid as I can. Keeping the body level will help there. 194450

These air bags definitely help with keeping the rear end higher than it would be (towing with a minivan, 300lb tongue weight), but as they are limited to 35psi, don't lift the rear as much as I would like. They are perfect for a full van by itself. Fairly easy install, only hard part is getting bags into coil spring. Air hose connections work very nicely. Used for 2 months and one 1000 mile towing trip so far. 20008
