Fitting of polyairs to 80 series landcruiser

Interesting, I've spoken to a couple of people regarding lifts and spacers. I've got the firestones in mine and cut the bump stops almost complete off, there's only the top bit left. I've got a 2 inch lift and don't have any spacers.
The theory I've been told, and seems to work fine on mine is that it doesn't matter have much lift you've got as the air bag doesn't actually stiffen the spring by supporting the weight directly, it does so by squeazing through the gaps in the spring itself. My bags don't touch the bump stop at all and it still lift the car as I put pressure in as it spaces out the spring by sqeazing through it. In fact it's better IMHO if you don't space it, because that way you are not limiting you up travel as much.

This is an interesting conversation.
I purchased my coil rites from All Air Suspension in Sydney and they advised me to use the spacers to compensate for the lift but your experience throws another spanner in the works.
As I say at work "I think we will have to investigate further"

Yeah when I first put them in I had standard height suspension and it was when I was pricing up the new shocks and springs for the back that a guy at my Local ARB (normally I take their advice with a pinch of salt I might add!) told about this theory. It made sense to me from my 18 months or so of experience with them fitted so when I finally installed my new suspension (not from ARB I might also add) it seems to work just the same as it did prior to the 2" lift. So there you go, I guess the ARB dude was on the money on that one... I also think that it will probally put less stress on the bags too as they are not being squashed against the bump stop all the time. But hey, that another theory...
