Insert broken record (that's the level of technology) comments by @EricTyrrell here!

Meanwhile; productive conversation inserted below:

@howirolla what's the years/hours/mileage/usage type on those bags; general estimate?

Don't know about you, but I've never seen a coil spring break. This is just the latest data-point in a long string of air-based suspension failures I've witnessed and experienced. Never again.

No doubt they have failures but generally well past their life just as any other spring/strut. If you think coils don't loose integrity over their life you are delusional! Do bags fail, rarely but we have all seen coil failures from shock coil lip failures and coil springs sag and no longer perform to spec and safety parameters. Properly maintained over the life they are almost zero failures just like when its time to replace a bag its time to replace a coil on a heavily ladened overland vehicle. Maybe just me but thinking coils don't sag under the load of overloading is almost comical. If you run it to condition, then yes it will eventually fail just like your shock/strut will eventually fail and can fail at the spring mount, leak, mount break, eyelet brake, pillow-block collapse.

Come on man; it's like every time you speak its with exception and never a simple google search. A simple search of your post history will show about a 98% negative comment rate; subtract that and you get bag failure rates at roughly 2% +/- outliers.

I'll wait to hear what the guy with the facts has to say; the OP @howirolla and not use generalizations or sensationalism to speak Wikipedia knowledge.

Keep drinking the cool-aid buddy. No honest and experienced person is going to make the case that air-bags or the air suspension components that they depend on, are as reliable and last as long as coils. It's pure fantasy and now you're on this irrelevant tangent about spring sag. "Failure" is key. Spring sag is an annoyance. Failure ruins your day.

As for your sag, I've had vehicles on 20 to 35 year old coils that haven't measurably sagged. I've also had coils of questionable quality that did indeed sag, but they didn't fail. There's a big difference in the context of remote travel.

Don't think I'm not aware that air-suspension has its advantages (the conversation you're trying to draw me into), but they don't negate their disadvantages either.

You must have missed the 20 other posts where I speak of the reason I have not gone to coils yet; how and why I feel air is better in some instances and coils in others but I surely have never said to any degree that one is wholeheartedly better than the other. My train of thought follows the same reason many and I mean many are changing out springs, adding lift spacers, etc. This kit meets the basic mark but not fully to the capability of the EAS which is why innovators like @Ray_G and a I think few others are experimenting with better spring options. Not enough lift; early shock eyelet bushing wear, too rough, too soft, etc. It's merely the only option we have at the moment, some are making it better though testing and innovation, and the rest of us are watching and learning.

Keep in mind, after a few years now we are seeing many reports of less than long life from the shocks in the AB kit. I fully support coils and you can bet your ****** I'll be on a set as soon as the "better" replacement is out there because right now I do not have EAS issues and I will be replacing to upgrade capability only; I do not believe at this point that AB has met that directly out of the box.

Eyes wide open my friend. Follow my build thread because there are some things in there coming up that will prove you wrong again!

Anyway, no hard feelings........

Air springs are in no way more reliable than a metal spring....or even the same.
You have the pump, lines, rubber that degrades faster then metal, sensors and electronics for height adjustment, and just generally more parts to the assembly which inherently increases risk of failure.
Yea....metal springs can degrade a bit over 30 years, but its easy and much cheaper to overcome a metal spring failure, if you actually ever experience it.

But that height adjustability sure is cool when on the lot, new.

The AB ad was a joke taking the piss out of airbags. The kit’s existence highlights the failure and frustrations of air suspension. Where there’s a solution, there’s a problem. Without getting into why, I’d never run a coil conversion setup. Sounds like you’re putting a lot of thought into improving them. Good luck. I don’t have the patience anymore.
