Features to know about

Stay Level When You Push a Plow: Front Suspension Air Support

When the front end dips under a heavy plow or other front-mounted gear, steering and braking can get sketchy. Firestone Coil-Rite air helper springs fit inside your existing front coil springs to keep the vehicle level and stable. With up to 1,000 lbs of load-leveling capacity, these air springs help maintain balance, steering control, and braking performance while reducing tire wear and keeping your headlights aimed right where they should be.

Smooth Out the Ride and Prevent Bottoming Out: Adjustable Air Pressure 10–60 psi

Every load is different, so it helps to fine-tune your suspension. The Coil-Rite system lets you manually adjust air pressure between 10 psi and 60 psi to match your setup. Add air for heavy loads or reduce pressure for a softer ride when unloaded. Independent side-to-side adjustment evens out off-center loads, cuts down on body roll, and absorbs road shock before it reaches the frame.

Built Tough for Long-Term Use: Durable Polyurethane Construction

These air springs are made from elastic polyurethane designed to handle years of work and road abuse without giving up support. They provide consistent cushioning under heavy loading and adverse road conditions, helping prevent bottoming out while promoting a smoother ride. Replacement springs are available separately if you ever need to service an existing kit.

Simple Installation and Reliable Setup: Everything You Need Included

The kit comes with all materials necessary for installation—air springs, brackets, hardware, air line, and separate valves for manual inflation. Just mount the valves where you can reach them easily on the bumper and you’re set to adjust as needed. The result is a balanced load, better handling, and suspension that works with you instead of sagging under pressure.

Video Transcript for All About the Firestone Coil-Rite Air Helper Springs

Hi there hard workers! Today we're going to be taking a look at Firestone's line of Coil-Rite Air Helper Springs for the front axle. You want to make sure you use our fit guide, so you get the correct airbags for your vehicle. Along with your airbags, you're going to get everything you need to get them installed. This includes your airline, your manual inflation valves, and zip ties, so you can properly route all those lines. You'll also receive any grommets or bushings that are required for your particular set in your truck. On our Ram here, we had one that went in the bottom that supports the bottom of our airbag.Air Helper Springs on your front axle is going to help support front loads.

These are typically things such as a snowplow, maybe you've got a front hitch or other accessories. Our customer's got a very large aftermarket bumper on here with a winch, and he likes to do a lot of off-roading. He's big into caving. So he has to do off-road some time to get to his caves. He's got his winch there to help pull them out.

And he's got a real big fifth wheel that he also halls.So in addition to the front airbags here, we also put a set of rear airbags on to help with this fifth wheel and in the front here to help with smooth out his ride when he's off-roading, and when he's helping pull people out with his winch. These bags are designed to go inside of your coil spring to help provide that additional support. They operate between five and 35 PSI and can support loads between 500 and a 1000 pounds per set. Now this does vary slightly depending upon your truck and vehicle. You want to make sure you never exceed the hauling capacities of your particular vehicle.I've got our airbags currently set at the lowest of five PSI.

We're going to hit the test course and see how they feel while our trucks unloaded to see if it makes it really stiff. Five pounds shouldn't make too much of a difference. We're going to go into our uneven bumps section first. This is going to mimic like hitting a pothole. Our back and our side to side movement is what we're going to be feeling here and it's very smooth.

Right now, it doesn't feel like we've stiffened up the front. It kind of just feels like it does from factory right now. It doesn't really make too much of a difference. And that's what we want when we've got them all the way aired down because that's what we're really not using them. We don't want it to adversely affect our truck.Next we're going to be going over the even bump section, which is going to simulate a speed bump or going in and out of your driveway and that's our forward and backward. And when our front hits the bump here, we go over the bump. It's nice and smooth. We don't have too many oscillations. It's not harsh when we come down. So everything seems fine there.We're now going to go into our slalom section, and this is where we're going to mimic an invasive maneuver. So with the five pounds in our bags, I kind of expect it to be pretty much just like a stock truck. It's probably not going to make too much difference, but often when you add airbags, it does help out with sway a little bit. You don't get as much body roll. So we're going to go ahead and get into it now and everything feels good. This truck didn't have a lot of sway to begin with. It already had a pretty stiff suspension. So everything seems nice. Doesn't seem to have changed whole lot there. We're going to go ahead and head back to the beginning of our test course now. We're going to air the bags up to max and we're going to see how they feel different.All right, we're back at the beginning of our test course. Now we've got 35 pounds in the front bags, and we're going to hit that uneven bump section first. And you can definitely feel that they're stiffer, but it's really not as stiff as I had imagined it to be. I really thought it was going to make this thing slam into these as it hits them. It does feel stiffer. It is a little more abrupt. The truck kind of is a little more jarring when it hits, but it's not nearly as bad as I had expected it to be. And our even bump section is still quite smooth going over them. There's less oscillations up and down when we come down off the bump. When we hit the bump, it is slightly harder, but it's really not too bad.And now we're going to head up to our slalom section and see if it's stiffened up the front any to make it a little bit less body roll. And you definitely can tell that it's stiffer there in the front. There is pretty much no body roll whatsoever with it now. It is a little bit too stiff for my liking. So unless I'm actually using it to do some work and get some stuff done, I wouldn't have the bags aired up this high, but they don't feel as terrible as I thought it would. So if you need to have them aired up while you're just heading to someplace, maybe you don't have a compressor system on it, so you've got to air them up before you get there. You're not going to have too terribly of a rough ride on the way there.One of the cool things about these airbags as well is that they can be adjusted independently from one another. So if you do have some uneven loads, such as something extremely heavy, that's just up on the left front or maybe the right front, you can air up that bag slightly higher to compensate for that. You'll receive manual inflation valves with your kit. So you can air them up independently from one another. Now I don't have them installed on this particular truck because our customer didn't want to have to get out his compressor and air them up. Instead, we installed a compressor system on the truck, so that way he can do it with a remote inside the vehicle.We've got a bunch of different compressors here at etrailer.com and I highly recommend Air Lift's Wireless Air System if you're planning on doing a front and rear setup. It's a dual pass system, so you can set up the front independently from the rear, so you can adjust those sets from one another, which is nice because typically you need more pressure in the back than you do the front, especially if you're going to be hauling a fifth wheel. And I also like that compressor because it's extremely easy to install.Airbags can also help restore some lost handling and braking performance that you might have from a heavily loaded front end because this as the front is weighed down, that's going to affect your braking because the weight is not going to be transferring the way it normally would. So you can help restore some loss breaking performance by leveling your vehicle back out and returning to the proper ride height. It also affects your handling because as the front's lower down, it changes the geometry of your tires. So you're not going to have quite the same surface area on the road that you did before. This can lead to excessive tire wear, as well as that reduced handling. Lifting it back up helps restore that geometry. So you get good tire wear and you have the best handling possible when you're hauling your load.Lastly, this is something you probably don't think about too much, but when you're front's loaded down and you're driving at night, your headlights are going to be pointed down towards the road. So you're not going to be able to see nearly as far in front of you as you would before. Using your airbags to help lift the front end back up to where it was is going to give you better illumination at night, so you can get home safely.And that completes our look at Firestone's line of Coil-Rite Air Helper Springs for the front axle.

Does exactly what is supposed to do however lifespan could be a little longer as I am replacing this exact product what seems to be somewhat premature.



by:

Fitment as stated and performed as expected. Easy installation.



by:

Worked great to keep front end level on my 14 Ram 2500 cummins with Fisher XV 2 plow.



by:

This is my first time using air springs on the front of my truck. They work well and were easy to install.



by:

I’ve had the red set before, for some reason this blue set, the supply hose leaks air.



by:

Reviewing products through etrailer is easy. etrailer sells top quality products at very affordable pricing. What you get at etrailer that you can't find at other companies is the BEST customer service you can find. I started using etrailer when I had an issue with another Firestone distributor. When I called Firestone direct to get the parts I needed that the other vendor would not sell to me (or even acknowledge my existence) Firestone referred me to etrailer as their #1 distributor. Not only did I get the parts shipped direct from the manufacturer, but they arrived in 3 days. I have placed more than one order and without fail have had the best service. Thank you etrailer !



by:

Pop all the time. I get about 6 months out of a set before I have to replace them... Good quality, just poor longevity



by:

Easy install



by:

Went in fairly easy once the springs were removed. Tight fit on the air connector. You must connect the hose BEFORE putting the spring back into the mount as there is not enough room to do it after. So far they work well.



by:

They seem to be working pretty.Well, the only thing I didn't like about the kit.Is a had to separate fittings did not have a t to tie them in together So I bought.
A t to put in line



by:

I have a small farm and to commute to the farm I drive about 200 interstate highway miles and 12 miles of bumpy dirt road with somewhat heavy equipment, my front shocks had to be replace twice a year and also right front off road tire on my F-250, after placement of the Firestone air ride helper(self doer, easy no more than an hour of work) my front new off road tires are wearing out like it should be, evenly (no bumps), no more expensive replacement of parts, and when it comes to handling on high speed interstate and city everyday commute, I'm very very satisfied. It also raised the front end of the truck about 1/2 inch, makes it look awesome. From my perspective on this product, no negatives remarks, for me all positive rating, highly recommended.



by:

Easy install just by lifting vehicle to open the springs. It has been a year since I installed them and the performance is awesome. Holds air for months without refilling. inexpensive way to improve handling. They are an amazing addition to a more secure ride.



by:

I installed the air helper spring on a small motorhome a Ford E450 easy eslallation work great thank for the good service



by:

Just delivered and everything looks gre at.



by:

Fast shipping from Etrailer. The job of putting them on was an effort for my 78 year old body, but manageable. Watched YouTube which provided valuable tips.



by:

I can not imagine anyone with a motorhome not having a air ride system. Increased handling and stability.



by:

Absolutely! The best thing I ever did for my 2023 Ford super duty F350 for plowing



by:

Could not believe the ride and handling difference. Should be on every motor on the road. Easy install at a great price.



by:

Just what I needed for my F250. Easy to install. I needed something to lift the front suspension while not towing or having a heavy load in the bed. Great price.



by:

A little tricky to get inside the spring. Hose clamps made it doable. Would purchase again if I’m in need of replacements. etrailer provided their usual excellent customer service!



by:

These air bags came with great instructions and I followed them but I also added a hose clamp over the bag to squeeze them down smaller and I had both bags installed in les than 45 minutes I was greatly pleased with the results. Add another 30 minutes to finish routing my air lines and adding the fittings. Very, very happy with this purchase!! Thanks etrailer for a great price.



by:

Bags are good quality but the fitting that screws on the airbag the air line hooks to broke so I am unable to use the air lines



by:

Easy installation did not even have to take wheels off race truck by frame the stretched out coil spring slit bag inside of coil hook up airline finished couldn’t be easier



by:



by:

Worked out good!!Installed new coil springs as well.
