Specs:
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.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
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
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
Mike L - 04/13/2019The 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
Easy installation, has worked as advertised on my Kia Sedona van. I carry heavy equipment and inventory for my mobile embroidery business and it definitely helps with leveling and stabilizing the load. 746587
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
Great product for Kia Sedona 2012 Towing my boat was heavy on car’s rear suspention. These airhelpers are great Easy to install 574073
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
So far so good, It's been installed for a month, carries the wheel chair with little or no dropping of the rear end. 439096
Firestone Coil-Rite still doing great. 363164
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
Review from a similar Coil-Rite in Vehicle Suspension
These air helper springs did exactly what we needed. We tow a Jayco Hummingbird trailer (3,750 lbs, 450-500 lb tongue weight) with our 2000 Toyota Landcruiser. Even with a weight distributing hitch the rear end squatted a bit more than I wanted. With the air helper springs installed rear end squat has been completely eliminated. Driving without the trailer feels more firm and connected to the road. The only negative is about the complexity of the installation. On the 2000 Landcruiser it requires that the rear suspension be partially disassembled. That was far more than I could handle at home. It took our neighborhood auto shop 3 hours to complete the job. Money well spent. 638942

Good product. takes some effort getting the bag inside the coils. As far as removing the frame bumper - didn't do it - it is pressed in between the frame and top of coil spring. So far so good 514375

I got the a draw tite hitch, wiring harness and Firestone coil helpers for my 2016 Nissan pathfinder. Everything fit great and was easy to install. The price was awesome and shipping was super fast. An easy A+ for etrailer.com. 343985

Did not work at all on my 11altima. No change to the suspension and the bags deformed beyond recognition after 2 weeks 260702
Review from a similar Coil-Rite in Vehicle Suspension
Easy installation fixed my problem of low ride height. The only thing I would change is I wish there was a 90° angle for the bottom so it doesn't stick so far out I know it's going to end up catching things on the road 595108

Working out very well 735132
Review from a similar Coil-Rite in Vehicle Suspension
I've installed the air springs and and they hold up great. I'm pulling a tall 5 x 10 enclosed trailer and no more sagging in the rear end. Air up the bags to 35 max PSI and the ride quality is excellent. 715974
Review from a similar Coil-Rite in Vehicle Suspension
We ordered a suspension kit it came right away and at a great price. We had checked out several shops in town who said they were hard to get for our new vehicle and the cost was out of this world. Great job guys 165779
Review from a similar Coil-Rite in Vehicle Suspension
Product installed without any issues. Do suggest taking a paper towel or rag and spraying a small amount of WD40 on it and wiping around spring coils only not on air bag. Bags slide in a little easier. Would have been 5 Star except for unacceptable shipping time, 5 days to on instate location 200 miles away. 579207
Review from a similar Coil-Rite in Vehicle Suspension
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
Review from a similar Coil-Rite in Vehicle Suspension
Used the Air Helper Springs on a VW Jetta to help when we put the 4 bike rack on it. Worked perfectly, kept us level when loaded and letting the air out gave us the ride when empty. Bike pump easily pumped them up when needed. I would recommend this product for anyone needing to control ride height under load or when towing to stiffen the suspension. We have had them installed for over a year. Way to go eTrailer! 240426

Review is for very helpful service- got into a time squeeze, made a call on Sunday, and received the correct part on Tuesday AM. No review on product yet, but it looks like it should work well. The go into the rear coils of a Toyota Sequioa and are currently being installed. 662780
