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 Nissan Quest, 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.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.

I was never able to get ahold of Firestone to get the one air bag replaced. I just have to fill up the one before heading home from the campground.

It is definitely frustrating to have the springs lose air. You may have done this already, however what I suggest is to take a spray bottle with soapy water and spray the lines along with the fittings to locate the leak. The leaking air will bubble up in that location. If it is the airline then re-cutting the line with a part like # AL10530 can help. If it is the fitting, then reinstalling it may help or might have to be replaced. We typically will carry the replacement fittings. They are covered under the warranty for two years. Please let me know which one you need, if you end up needing one.
one of the valves failed and we had to reinstall 3 times. We had to order extra parts at my expense (an additional $20). It just was finally fixed. Not sure it's worth the trouble
etrailer has no business being in business. The customer is your business. And I for one, won't be doing business with your company anymore. Not a happy customer.
Very simple design for preventing rear sag when weight is loaded on the tongue. Installation was ok, with the most difficult part being actually getting bags inside the coils. Look to online for help as the instructions are generic and not great. Would recommend getting the t-splitter 1/4 size to get a balanced ride. Only complaintS are the output valve points downward which then Puts your airline closer to the ground than comfortable When driving.
Exactly what I needed, work great, Thank You etrailer.com!
They work good put 20000 miles on car and have no issue. The squeak a little once in awhile but only noticeable when window down. They are much easier to put on with car jacked up and tire off.
I had these on last car and they worked great
Simple to install and does what it says.
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,

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.
Installation on 2014 Pathfinder didn't require Shock removal. It went in fairly easily. They are helpful although wonder if they shouldn't be slightly taller . With 5 passengers and trailer approx. 3500 lbs. still sags some. In my opinion Japanese cars all have Weak rear suspensions

How did you install with the stop built into the top spring seat? Also did you run the air hose out the bottom? Thanks

To Will , To be honest, I didnt even look at the upper inside of the spring for a stop . I simply collapse the bags and worked them into the spring . Yes I have the air fitting and hose coming out of the bottom . I used extra cable ties to secure the hoses. I drilled NO holes in anything. I was carefully of routing the lines away from the heat of the exhaust. I mounted the Air fittings to the holes in the receiver. One complaint is that I have great difficulty in filling the them. I dont know if it is the Tire chuck I am using or the Fittings provided. I actually end up unscrewing the nut on the fitting and take the fitting and hose free from the receiver to press the tire chuck on far enough to fill them then remount the fittings to the receiver

They work great, only thing is I do have to put air in them every few days other than that I’m very happy with them I’ve had my Jeep grand Cherokee loaded down and it didn’t squat at all
Hi. As requested bu etrailer, this is my one-year review.
Overall, works very well. Both units are in good shape, still hold air pressure, They have been on constantly for 4 seasons including our Canadian winter, and no issue. I added some grease on it to minimize friction with coil spring.
The only thing that does not work properly is that one of the hoses, which was routed from the spring valve to the supplied inflation port installed on the bumper, does not work, does not inflate spring. I don't know what the issue is, but I have to inflate at the valve directly, which sucks to access.
Thanks
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.
I put these on a 2017 Nissan Pathfinder 4x4. I pulled a 4500 pound single axel camper 30k miles with NO issues. I took it through the osceola national forest (if you know, you know) Never bottomed out and smooth as butter on the ride. I paired the inner coils with a husky weight distribution hitch. The helpers gave me about 1.5 inches off squat when at 20psi. You also do not need to run the air lines unless you just want to. I only needed to add air 1x when seasons changed. Great product.
Worked well, but required drilling a hole to accommodate the stem, despite an indication it was compatible. One bladder then failed after about a year, due to a manufacturing defect. Firestone promptly sent a replacement, but it was a hassle to remove and re-install a new one.
We have a Nissan Pathfinder that is more than capable of handling the tow weight of our boat and trailer, but the suspension is definitely designed for a smooth ride over towing, so hooking up the boat left us with a definite dip in the back. These air helper springs did the trick and were so much easier and less expensive than replacing the suspension!! They made towing the 21 foot boat with trailer much easier and safer.
Bought this for our Toyota Sienna, it helped a bit but one side leaks and has to be aired up anytime we have a full load.

I would check your air lines. Make sure that your connection points are flat and level with no abrasions. Get a spray bottle with soapy water and hose the sucker down and see where the bubbles are coming from.
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.
Great product arrived in time as always
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.
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.
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.
It's helps with the control of rear weight. I hauled a trailer across the United States with a Pathfinder and used these. Without them, the vehicle would of sagged and took every bump.
Great support for suspension while pulling my boat with our pathfinder. Easy instal thanks to etrailers videos.
