I ran 2x fridges, enough tools to equip a small workshop and towed a 2t boat with my D2a from Geraldton to King Ash Bay and back on coils without any problems.Quote:

Coils work just fine[thumbsupbig]
Where the plastic line goes into the push in fitting, the cut has to be square and without distortion to the circumference. A proper tool can be sourced from a truck parts outlet, cheaply.
X2, buy the bags, I am the guy that is installing airbags! Too much variability with the coils and different loads.Quote:

And if you check the buses, you'll find a very strong likelyhood that all axles will be air suspended.
My brother's D2 had a half decent run on some coils, but they don't last forever as many seem to think they do.
My old RRC had a good run from it's coils, and again they didn't last forever.
So the comment that coils work 'just fine' can equate to quite a few variable meanings.
from 'at least they haven't yet snapped' (like in my RRC) too ... 'they haven't yet sagged to uselessness'(like on brothers D2) .. where the replacement coils made a startling difference to how the vehicle drove subsequently.
The advantage of airbags is that they either work or they don't .. so where coils may work just fine .. it may not be ideal like a air bag would be until it fails.
My guess would be that with 100K klms and all the heavy work you've used them for .. at least one the 4 coils will have degraded in some way. Maybe not much, and possibly not noticeable all that much, but will have an effect on handling, that air bag springs won't.
X2 ……..even though I don’t have SLS on my D2, if I did I would be very inclined to retain and maintain the system much the same as I have done with ACE which I wouldn’t want to be without.Quote:

There is a little brass collar that the line goes into on top of the bag, push the air line and the brass collar in together, then hold the brass collar in while you pull the line out... Simple!Quote:

Have found Contitech brand outlast Dunlop but cost a little more.
and if it does not move?Quote:

The SLS system is not complex and easily fixed when broken, there are many posts on troubleshooting etc.
Even the pump can be spruced up with new piston ring and "de-humidify" balls.
I don't get why people think coils are the way to go but I expect its because of old style urban legend stories about how unreliable air bags are.
