It's no problem at all provided you've got the roll-stiffness elsewhere. L322 and later vehicles all do it.

On a live axle? Apples and oranges

It works well offroad, not on road

Well yeah. I thought that was obvious enough to not mention. A valve on the cross-link line is on all the factory setups.

Is it on you classic? how about P38? how about any factory live axle setup?

Classic and P38 don't have any off-road cross-linking (no off-road mode to trigger it I guess). But they do apparently bridge the front bags to equalize pressure in some situations.

The progressive nature of the air bags gives them a lot of roll-stiffness. With the EAS computer unpowered jacking one corner of the EAS classic gives a lot less articulation than the coil classic. But offroad it seems to have no problems keeping wheels in contact.

Others have cross-linked P38's. I'll give it a shot on the classic when I get my manual inflation lines hooked up.

I asked this question in another thread, the one on Tony/Rangierover 120, I think.

Tony was using air springs and a X Eng Disconnect sway bar (which he broke) I asked if a better way way might be to have a fixed sway bay and cross link the air springs (off road), but it got lost in the chatter, I think.

In Vic converting from coils to air require engineering certification, as Rick said I don't know if the Airbag Man kit has some sort of type approval.

The sway bar got damaged due to the extension we put on the mounts, tony copied mine and got the same flaw, mine also bent

Cross link works in offroad, kinda, you can only do one end, a mates tray had bagged rear and solenoid to crosslink, in the end though it was not worth it, to tippy, your better off forced articulation, ideally a pendulum and good control will be the go

Anyhow, at dougals rate it will be 2056 before he tries anything

2020 easily. I don't apologise for having a life competing for my time and money outside rovers.
