Firestone Coil Rite Review – What you Need to Know

Thinking about grabbing some airbags for your sagging rig? Check out this Firestone Coil Rite Review and see how quick and easy it is to eliminate sag in your vehicle for less than $100 and less than 2 hours of your time to install.

Firestone Coil Rite and Vechile Sagging

Want to reduce sagging when towing with a 5th Gen Toyota 4Runner?  Wanting to take your 4Runner on an overland adventure?  Wondering how to reduce or eliminate the sagging that occurs in the rear when loaded without breaking the bank?  Look no further.  Here we check out the Firestone Coil Rite Air Bag solution to these problems.

As I prepare my 2019 4Runner to tow a teardrop off-road camper (roughly 2000lbs), the first obstacle I wanted to tackle was avoiding the sagging/squatting in the rear once hooked up/loaded for our family adventures. I mean, after all, does anyone like the look of a sagging truck? I sure don’t, call me OCD, whatever, it matters to me.

I realized that the load of the trailer, mixed in the weight of gear in the rear cargo area would lead to the rear of my vehicle to squat, causing the ride of the vehicle to be off and some uneven tire wear to occur.  My quick solution was to install the Firestone Coil Rite Air Bag Helper Springs, and I’m glad I did.

If you are not mechanically inclined, don’t stress!  The install is easy and if you are Overlanding, camping, or going off-grid camping you should probably already have the basic skills needed to perform this task.  And if not, there is always YouTube! 

Check this out for a good walkthrough. I chose the method of lowering the rear axle to allow the coil springs to extend, making them easy to remove.  It also made cutting the rubber bumper stops much easier, as well as running the airlines. 

Once I had the bag installed inside of the coil spring and with the help of a friend, we reinserted back onto the vehicle and then headed over to the other side to repeat!  Secured the airlines with included strap fasteners, installed the Tee Union (additional $6.95), which combines both airlines into one, and job complete. 

Firestone Coil Rite Install Time

The overall installation took us an hour and half.  While there is no drilling required, I decided to install the Tee Union to the top inside lip of the rear bumper for ease of inflation/deflation.  This also allows the inflation/deflation valve to be protected from the elements as well as yourself. 

Now, this was the first hole I have drilled into my vehicle, which gave me a little anxiety, as I’m a little OCD, but it came out very clean and I’m happy I decided to do this.  Inflating is simply performed by using a bike pump or air compressor.  All in all this was quick and easy, very glad we took the chance on the firestone airbags.

What we Gained After Installing the Firestone Coil Rite Air Bags

This product provides 500-1000lb load-leveling capacity, which solves my needs and everything I plan to throw at my 4Runner.  We also no longer have the dreaded sagging when the vehicle is loaded up with families and gear. The look alone of a sagging truck makes me nauseous and to be frank, for an under $90 solution, this modification will pay long-term dividends.  


This addition to my rig only cost me $90 and was free to install. Additionally, it gives a bit more clearance when off-road or pulling my trailer to a new remote camping spot. Not to mention, I hate sag in my truck, and now it’s gone. Is the Firestone Coil-Rite a good buy? I think so, it has been on now for thousands of miles and I’m happy with it!
