Tucker Snowcats use ARB’s in Dana 80 rearends
In that application they were very troublesome, if the temps got down to about -30 or colder the two O-rings inside would fail and bypass air . This would in turn pressure the diff case and would come out the vent until it plugged with ice and then the axle seals would fail.
It’s also a proprietary o-ring that you can only get from ARB and was very hard to get because the Dana 80 was not a super common application for them.
And of course the lines and fittings , it’s all metric which can be a pain in the ass to source . Other than from ARB . I have a 200ft spool of it now that was able to get on Amazon.
But with that said My ARB’s have been pretty great I have one in a Rockwell axle , and one in my 98 Dodge
