i test drove several coil sprung vs air sprung d2 before electing to buy a coil sprung d2 for a few reasons:
1-i liked the way the coil sprung rear end matched the front
2-i felt the engine generated more power without the 2nd air compressor drawing energy from it
3-i'd have tossed the air springs for my rte 3+" lift anyways

am i imagining #2?

Yes, yes you are. That is a small 12v compressor under the drivers side floorpan. Doesnt draw much power, and its only on for a moment.

i will hand wave. the coils are much better, period. there is no need to "check the numbers". coils wont leave your ass stranded on the fucking trail. if you think that the EAS is better, especially over all, you should be checked out by a physician for dumb fucks disease.

They both have there pro's and con's, and only the owner of the truck can decide what is best.

I removed my EAS and have regretted it everyday I drive the truck. The EAS never left me stranded, but my fuel pump did, my radiator did, my starter did, and my failed tensioner pulley just did this week. If you like it then keep it, and just understand that like everything else on these trucks it will fail too. At the time I removed mine, there were not many support options other than the dealer, and I was not going back there, but that has changed now, and there are many more options avail so you can service it yourself. I am considering putting it back on and ditching the coils.

In hindsight, the EAS was the least of my problems with this truck.

really? I could have swore i saw another belt driven compressor on the motor- I could have well been smoking the crackpipe at the time...

That was the ACE pump. ACE has a separate pump that is belt driven. EAS as on the RR and LR3 use an electric motor driven compressor.

I like the simplicity of the coils, but EAS is hard to beat for ride and articulation (stock to stock). The LR3 and new RR cross linked EAS articulation is really unbelievable. It is really a simple and reliable system, IF maintained. Would I go through the Rubicon or other trails with EAS? Yes, but I would carry appropriate spares like a front and rear bag, o rings, line, and a controller.

mcnabj seems to share the same convictions as i. however, i do agree that the tech support and aftermarket alternatives have increased and improved leaps and bounds. even so, contemporary aid and parts do not compensate for its failures. and even more so, why would you want the EAS failing if everything else is following suit?

well said.

I really didn't want to reply - because you guys are on an ignorant side of rover ownership.
There is a difference between running the complete EAS, or airbag suspension.
Airbags themselves have proven to be unbelievably reliable - they are used in most big rigs on the highway, for hundreds of millions of miles annually, and heavily loaded.
Fuck, airbags are nearly as reliable as tires - somehow, nobody I heard arguing about going back to wagon wheels.

This "simplicity" argument is as dumb as it gets. As dumb as advocating a carburettor and points ignition on an engine with a perfectly functional EFI system. The perceived simplicity is only within the scope of one's technical knowledge - if you don't know how to use a multimeter, of course everything electrical will sound complex and unreliable.
Guess what, it isn't.

I heard Luke making the same simplicity and reliability argument on the same subject before (do your search). His arguments included examples of race trucks - an argument barely applicable to a rover. First, it is difficult (although not impossible) to design a long-travel air suspension. Second, maybe the dudes in countless desert race shops around Southern Calfiornia just like to follow the other dudes' smart advice?
Citroen was running a hydro-pneumatic suspension on their race cars in Paris-Dakar rallies for forty years now.

Now, to answer the last dude's comment about what to do with a failed airbag - on a Classic, the longest part of replacing one is taking the wheel off and putting it back on.

peter you should do some board research and find out what people have said about your theory of EAS (airbags) being analagous to the bags used on a semi. if a race truck isnt applicable to a rover, then how the hell is a big rig? I know what the fuck to do with a failed airbag on the trail as well. my point is with a coil that need is not present. by the way, i am not ignorant, i just dont like to make things harder than they should be. dotn be a fuck face and poison everyone else with your self proclaimed esoteric rover knowledge fuck face. but hey, you are right peter. all the UROC and WEROC buggies and Camel Trophy trucks were EAS suspened b/c it is great! yeah right. the last things one needs to worry about is a fucking zip lock baggy leaking 100 miles from no where; especially a place to get an EAS part.

Enough said.

I have never wanted to wheel such a tempermental suspension. the money you spend on repairing bags after running difficult trails for a year will buy you new axles or lockers.

Peter:
I have to question this one Peter-keep in mind that you live in California. In Indiana where they salt the roads, things go awry quickly.

The last Classic I converted was from Chicago where they use more salt than Indiana! I had to cut the old bags out.

The last P-38 I converted, I had to use a hydraulic porta-power to get the wheels off, they were corroded so badly. All of the springs had to be chiseled out as all of the retainers had seized up.

I'm no fan of EAS, but I'm not gonna get into today:D

That is true.

But it is true for the rest of the rover, built out of steel and aluminum and nothing on the way to prevent the electrical contact betwen the two dissimilar metals.
Like you said, the same stuff happens even between the wheels and the hub surface - and it can (could) be prevented by some maintenance. Like coating the steel surface with a minute amount of grease before bolting an aluminum part to it.

This has nothing to do with rubber itself. Again, airbags are nearly as reliable as the tires.

Salt does just as much damage to steel vehicles!

I'm not sure that tires are a suitable analogy. Who keeps tires as long as most keep their airbags and expect them to work as long and as well? I've never even tried to use the same tires for more than ten years.

damn, you mean salt eats away metal over time?! you are right about the tire analogy too.
