Firestone Coil-Rite Air Spring Basics

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.

Video Transcript for Firestone Coil-Rite Air Helper Springs Review

Today we're going to be taking a look at the Firestone coil rite line of air helper springs. Be sure to see eTrailer's fit guide for your application.Our springs are designed for a wide variety of vehicles. They're going to fit most passenger vehicles, vans, some light duty pickup trucks and motor homes. Whenever you haul a heavy load, have a lot of equipment in your vehicle or have a heavy trailer hooked up to it, it's going to cause the back end to sag down which is putting a lot of strain on your rear suspension, not to mention you're taking the contact off the front tires and misalignment your headlights. Our coil rite springs are going to take a lot of that effect out and help the sag in the rear end.Your air springs may look a little bit different than we have here, so you want to make sure you check each other's fit guide for your specific application, but these are going to provide us a smoother ride for vehicles that have coil springs in the back. They're designed to fit inside the spring, which is going to create a variable spring rate and help prevent the sag when we're loaded down and take stress off the rear suspension.

Our springs are going to be made out of a polyurethane, so they're going to be durable and last a long time. They are rated for working in temperatures from negative 40 degrees Fahrenheit all the way up to 180 degrees Fahrenheit. Each set is designed to support 500 to 1000 pounds and having an operating range of five PSI all the way up to 35 PSI.One thing I do want to mention is that our coil rite springs are not going to increase the payload of our vehicle. They're just there to help support the extra weight. So you always want to double check your vehicle's owner's manual and never exceed the manufacturer's recommended weight.Compared to other style of EHRs springs these are specifically made for the coil spring suspension, opposed to the leaf spring where that would sit on top.

These are gonna help out a lot with the SAG and prevent bottoming out and give us a smoother ride even when we're unloaded.Our kit's gonna come with two manual inflation valves. That way the bags can work independently from each other so we can inflate each one to our desired amount. That's going to help a lot with those off center loads, or if we take an evasive maneuver, it's going to take out some of that body roll. Our helper spring kits is going to come with everything you need to get it installed. Both springs, any brackets necessary, the lines, and the inflation valves.Ryan wrote in saying the install was easy on his 2014 FJ cruiser.

A year later he wrote back in and saying after a year of regular use, the bags had been great. They keep as FJ level where he's towing, and as a result, the steering while towing is vastly better.If you've had the back end of your vehicle sag down, rough ride, uneven tire wear, or even misaligned headlights our coil rite springs are going to help out a lot. All while giving us a smoother ride.

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 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.

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

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

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

The F4170 kit does fit a 2009 Hyundai Santa Fe. However installation is not quite as simple as the video. In order to remove the jounce bumper and install the air bags on our All Wheel Drive the springs needed to be removed. The instructions show a 2" piece of air line at the bag and then a 90 degree union. Make that 1.5" and the union will not hit the top of the steel jounce bumper cup. Insted of a 7/16 inch hole for the lines, go bigger and put in a grommet so the line does not rub. I went to 5/8 inch and then used 3/8 fuel line to cover the air tubing. Protects it from getting cut and from heat at the muffler. I agree that the top spacers need work. No real retention or centering on top of the bag. I put RTV silicone on the spacer and then placed it on the air bag. It centered on the bag and it should stay put. When the vehicle is off the ground and the springs are at full extension, and the jounce bumper cup does not touch the spacer. With the bigger hole, the fuel line guard, and the RTV I hope the work for a while. If not the bags are lifetime warranty and the hardware has 2 years. 98925

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 from a similar Coil-Rite in Vehicle Suspension


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

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

Excellent product, installed on 2011 Toyota Sienna that tows 3,000# Hybrid Travel Trailer. Works great to keep rear level (along with Anderson Hitch Weight Distribution). We now run air in them without the trailer as well to help prevent typical Sienna sag when loaded with people or loads. 252191

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 139152

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

Thanks for responding Larry. In the installation instructions Firestone recommends removing the factory jounce stop, or spring seat before installing the Air helper springs.

The lines need to be cut very cleanly and perfectly square. If there a little crooked or rough, the fittings cannot seal to the line. If you are using a knife or box-cutter or side-cutters to cut the line, your fix may simply be a proper line cutting tool like parts F9009 or AL10530. Make sure when you push the line into the fitting, that you push it all the way in until it bottoms out.

Etrailer was fanatic there communication is great and follow thru Install was a bit harder then other reviews say it is as far as getting the air bags inside the coil springs .I ended up taking the coil springs off the car for install not hard just time .after air bag install the rest was a peace of cake .With 35 psi in the air bags car was a lot firmer rode better and handle better then stock .Still the vw sport wagon is weak for towing tong weight .But the air bags are a must have if you tow anything or even carrie a bike rack 105672

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

The product is not exactly as pictured. The bottom protectors are disks (round) rather than rectangular. But that doesn't affect their installation or performance. Installation was a bit of a challenge. I'm not a gear head, so I was lying under my 2008 Rav4 trying to jam the bags into the springs. I started on the driver side. It went fairly well. The passenger side was a different story. The exhaust system was in the way -- good thing it was coolish. I did manage to get both bags in with all my knuckles still intact. The instructions indicate that you cut a short piece of hose, insert it into the bag, deflate the bag, and insert the plug in the end of the short tubing. That's fine... but then when you get the bag in, it says to remove the short tubing. Ummmm.... how!?!?! I did manage to get the tube out of both sides. I'm not sure, but I think I may have buggered up the quick connector in doing so. The second to last step is to run the tubing to the back of the vehicle. I'm not too sure I've done a great job running the tube. Since the tube sticks out the bottom of the spring and arm, it seems there is no way to get the tube so that it's not dangling down from the car. On the passenger side, the exhaust system is very close to everything. It was hard to find a place to run the tube that wouldn't be too close to the exhaust pipe. Then you need to check for leaks. My unit's max pressure is 35psi. I inflated it to that, and quickly heard hissing from one side. I removed the quick connect inflator and reinstalled. Still with the hissing. So far, I haven't been able to stop the air leak. But... they stay inflated at 25psi. For now, that's okay for my application. Then you're supposed to drill 2 holes in your car. I don't think so.... I left enough tube that I can decide later where to install the inflators. For now, they're zip-tied to the hitch bar. I plan to get a piece of metal that will attach to the hitch's mounting plate, and drill through that instead. I haven't been able to tell if they perform as advertised. I just finished installing them earlier this evening. I took it out for a test drive (just to make sure I didn't mess up anything). Inflated at 25psi it seems to drive fine. I can't tell if the back end is firmer.... or if I'm just sensitive because I'm aware of the bags being in. It does appear that the back end rides higher (even when it's empty). I'm loading up in the morning and heading out. I'll update my review with performance observations when I get back. 94306

Use a concentrated soapy water solution in a spray bottle and start check the areas where the hiss is coming from. If you have an audible hissing sound, it will not hold pressure for long and you do not want the coil springs to be moving on a flat bag.

Thanks for the awesome customer support.Making a fresh cut on the inflator end helped. The hissing has stopped, and no more leaks have been detected.I just got back from the maiden road trip 350 miles round trip. Its certainly not a long road trip, but it was enough to notice the dramatic improvement.Normally, when I attach my travel trailer 3500 GVW my Rav4 with tow prep option sags in the back. My trailer has the weight distribution kit that helps level it out. But, it only helps with the trailer weight. When I carry SCUBA equipment in the back of the Rav4, it still sags, and the weight distribution kit doesnt help with that.But... With the F4174 Coil-Rite air springs, there is very little sag. In fact, I was able to attach the trailer without much sag at all before I attached the weight distribution bars. With the SCUBA gear in back, the Rav4 stayed level no visible sag.In fact... the hole towing experience was dramatically improved. The ride was a lot smoother. There was a lot less galloping. I hardly felt the bumps on the road.Im surprised that Toyota doesnt offer this as an option. That such a simple and inexpensive alteration could make such a dramatic improvement is really surprising.I would like to change my rating to 5 stars.

We are glad to be of help. Remember to check the tongue weight rating of the RAV 4 in the owners manual. The tongue weight of the trailer and any cargo in the RAV 4 behind the rear axle will count towards that capacity. The air springs working with the weight distribution should make for a much better ride and your RAV 4s suspension will certainly thank you for it.

-- Patrick B - 8/14/2013

The good news is... These are awesome and should be available as an option from the factory. With the back end loaded and the trailer connected, the rear of the Rav is still off the ground. It also improved handling as the front end stays on the ground.It turns out that I hadnt buggered the quick release. I had just cut the hose at an angle. You need to make sure you cut the hose square. After cutting the hose square, the bags stay inflated without hissing.The Bad news is... if you have work done around the exhaust system requiring a cutting torch, you need to be careful and have some sort of shield to protect the bag and hoses. I discovered this the hard way. A small piece of molten metal cut through the bag like butter.But, for some reason, putting the 3rd bag was easier than either other the first two.I wound up attaching a small piece of angle iron to the hitch bar. This worked very well and avoids cutting the hole in the car.Having the tubes dangle from the bottom of the car hasnt been a problem. I was able to tighten them up a bit and route them better once the angle iron was installed.This has made a big difference

Review from a similar 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

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
