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.


Firestone Coil-Rite airline installation

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.


Firestone Coil-Rite air spring components

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.

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.

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

2010 Nissan Pathfinder

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,


Comments
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.

2014 Nissan Pathfinder

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.

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


Comments
How did you install with the stop built into the top spring seat? Also did you run the air hose out the bottom? Thanks
-- comment by: Will - 08/13/2014

Comments
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
-- comment by: Larry M - 09/30/2014

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

2013 Nissan Pathfinder

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.

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.

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.


Comments
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.

  • Recommended Parts to Tow a Trailer with a 2015 Nissan Pathfinder
    You are definitely on the right track when it comes to everything you need for towing with your 2015 Nissan Pathfinder. The Firestone Coil-Rite Air Helper Springs # F4118 is a good idea to help with sag, but we always recommend using a weight distribution (WD) system for any trailer that weighs more than half of the curb weight (unloaded weight) of the tow vehicle. A WD system will help with sag because it distributes the total tongue weight (loaded tongue weight of the trailer and...

    The Firestone Coil-Rite Air Helper Spring Kit # F4118 you mentioned for your 2020 Nissan Pathfinder will not lift your vehicle, but will just provide between 500-1000lbs of load leveling support to fight suspension sag when towing a trailer.

    I would be happy to help! Nissan's response was what we call clear as mud. I have no idea where they are getting that you only need a weight distribution hitch if a load is 8000lbs or more, as that is not any sort of industry standard weight. I recommend checking the trailer hitch receiver of your 2014 Nissan Pathfinder for the load rating sticker, and seeing if it mentions a weight rating for weight distribution hitches.

  • Air Bag Helper Springs for a 2015 Nissan Pathfinder Towing a Travel Trailer
    Suspension enhancement will help with the rear end squat on your 2015 Nissan Pathfinder. SUVs tend to have softer suspension compared to most trucks so even when using weight distribution some squat can still happen. For your Pathfinder # F4118 is the only option. When you are ready to start towing couple the trailer to the vehicle like normal. Then adjust the air springs as needed. I have included a link to the installation details for you.

They will both work well to reduce sag but the air bags are a much better option since you can reduce pressure while not in use for a factory ride.
