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.

The Air Helpers are a real bear to install, took me 5 hours and lots of ingenuity but it's done now.. They are a very dense, thick, flexible material that are extremely stiff and don't go easily (a huge understatement) between the coils to lodge inside the springs. They are quite low volume so be careful to inflate small amounts at at time until you reach the desired pressure. Haven't had them under a load yet, but if you manage to get them in place I expect they will provide stiffening as advertised.

Not really helping, and theres a slow leak in one of the systems.

Good product. Kit is complete. Doesn't resist well to potholes. Not so easy to install. Even more difficult to remove and replace. A good challenge for a week-end mecanic.

2008 Mitsubishi Outlander

Product does what it says it will do for my 2008 Mitsubishi Outlander. Had a leak in one of the bags but Jean at got me connected directly with Fire Stone. They got a replacement out to me ASAP. Very happy customer TY The picture shows the extra weight I have on my SUV.

Review from a similar Coil-Rite in Vehicle Suspension

Installed on my 2020 Ram 1500 4x4 ecodiesel. Took about 1 hour. Jacked up rear of vehicle to let coil spread out a little. Bags went in easy. Air lines were simple to run. Bought the union T-valve so I could air the bags up at same time and to make sure equal PSI goes to each bag.

They still working great. Only minor issue is the line that threads onto bags do come lose and cause air leakage. Recommend locktite to solve the issue.

Review from a similar Coil-Rite in Vehicle Suspension

These work great for the VW Atlas!! They reduce the rear end sag when pulling a travel trailer or putting the roof tent on and loading all the gear for some overland trail riding and camping!! They are a must for any adventurous Atlas Owner!


Review from a similar Coil-Rite in Vehicle Suspension

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.

Customer Service will reach out to you about the warranty.

Review from a similar Coil-Rite in Vehicle Suspension

No issue at all with these. Keep them with at least 10-15psi at all times and lift it up to 30psi only when fully loaded or hauling. Initially, the blue fill tube seemed too long but worked out great to get it laced underneath the exhaust heat shield. Some have put the fill valves on the inside. However, I found it easier to use a standard bike pump on the exterior. And made it symetrical :)
I would had have recommended it to several others who have simular needs.


Review from a similar Coil-Rite in Vehicle Suspension

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.

Thanks for reaching back out about this. I have gone ahead and sent you an email with some more contact information for Firestone.

Review from a similar Coil-Rite in Vehicle Suspension

They functioned exactly as advertised. Very strong and durable. So strong are they that they didn’t even burst or puncture in a roll over crash. One of the spring that contained a spring assist bag was knocked out of the truck and it still did not rupture.
In the pictures below you can see the spring in the bed of the truck.
Highly recommend this product.


Review from a similar Coil-Rite in Vehicle Suspension

They work great. First I added a levelling kit then the Firestone ride rite for when I tow my boat. Really notice the difference when towing.

With fully loaded tongue weight, rear suspension dropped .75 inches, added 10psi to the bags and brought it back up .5 inches.

Its been great one of the best additions to use when towing. I recommend it for anyone that tows or adds excessive weight in the rear.

Review from a similar Coil-Rite in Vehicle Suspension

Installed on a 2016 4Runner in conjunction with a 1-1/2" Daystar coil spring spacer. Since the coil spacer is hollow, I left one segment of the factory bump stop in place to compensate for and match the height of the spacer. I also added a Firestone T-fitting on the airline for a single inflation point and located the inflation valve next to my trailer plug wiring. Quite a pain to wrestle the coil back in place with the added height of the spacer, but that is no fault of the airbags; pry bar proved critical to wedge the coil back in place since I did not try the bottle jack between the frame and axle trick. After nearly a year, no leaks, bags hold air well. I put 25 psi in them for towing our travel trailer, or keep them at 10 psi for normal running around. I have also found them useful to prevent or at least reduce bottoming out the soft rear suspension that happens when off road driving with even just a couple hundred pounds in the back. Even at 25 psi they ride great and you wouldn't know they are back there at 10 psi. Highly recommend for the low cost and added versatility!

Still working great after a year. Knock on wood... no leaks to date. I would consider these essential equipment for towing, and would highly recommend for heavily loaded backcountry travels as well. I did try them near their max pressure on one trip with 5 people, roof top tent, and gear for a week of camping this summer and it was too much and felt very unsafe ped the pressure back to sub-30 psi after driving a few blocks and all was great after that!

Review from a similar Coil-Rite in Vehicle Suspension

I added these to my Trailblazer ext after I lowered it 2/4. I pull a 25ft pontoon and a heavy duty equipment trailer that weighs 2500lb empty and I've never rubbed and it keeps the bounce to a minimum. Installation was easy.


Review from a similar Coil-Rite in Vehicle Suspension

They want a review 12 hours after delivery :-(
On a 40 degree day I had to drop the shocks and swapbar connections and then jack down the axle housing and remove the springs and drop the bags in from the top. The bags are just to solid, even after warming them up inside the house, to go thru the side of the spring. It doesn't take all that much longer to remove the springs. You just have to be aware of more ways that hoses, cables, and such could be hurt.
The ride is stiffer, even at 5# of air. Measuring rearend sag they should be able to deal with the load my trailer tongue when aired up to 60#
I would have waited and done a better review but they couldn't wait to bug me for comments


Review from a similar Coil-Rite in Vehicle Suspension

Install was easy on 2014 FJ Cruiser...pulled the wheels off, jacked it up a bit, and the axle dropped enough to allow room to fit the bags inside the springs. I will see how they perform when I hook up my trailer but they inflate quickly and I can see these will stop my vehicle from squatting when the cargo area and trailer are heavily loaded. Another excellent product offered by etrailer...thanks.

After a year of regular use, these bags have been great. They keep my FJ level when towing and as a result steering while towing is vastly better.

Review from a similar Coil-Rite in Vehicle Suspension

The gabs arrived with a leak in one and it took over 12 months to get a replacement from Firestone .. which also leaked. eTrailer was no help in resolving the problem - they just redirected me to Firestone and the unmotivated and poorly organized staff there. If yo buy these, get them at [online]- that company stands behind the product they sell.

It is very unusual to have two air bags that would be defective from Firestone. Typically what can happen is the air line hose is not cleanly cut or is cut at an angle which can cause leaks over time. I recommend checking the hose and using a hose cutter like part # AL10530 to ensure clean cuts. I also advise using the soapy water method to locate any leaks. You can just spray soapy water on the air hose lines and see see if any bubbles form. If they do then you will know where the leak is coming from.

Review from a similar Coil-Rite in Vehicle Suspension

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!


Review from a similar Coil-Rite in Vehicle Suspension

Product works as advertised. Surprising held most of its pressure after a year without further inflation. Provides very good suspension assistance when trailer tongue hitched to minivan.

Air bags are still performing as expected. The additional surprise is how well they hold their pressure with time. Thanks again for a very good product.

All parts there to install, no buying necessary parts that are not included. Instructions and video will make installation straightforwRD

Working great, keeps tail of car at correct height. Cut the air lines when installing as directed. Do not use sidecutters.
