Yeah, the OME Sport shocks are great - have them on my D40 and would never look back. My mate who runs the ARB store in Canberra offered them to me at a very good price as they were the first set to be fitted to a D40 in the Canberra region and they wanted the feedback - good ride quality/handling compromise...and that combination is ALWAYS a compromise...
I would disagree with you on one thing GU - you don't need your paperwork with you for after sales backup anywhere in Aus - all you need to do is remember where you bought your gear. I've found ARB outlets very helpful, and they will call the outlet that sold you your gear ad check details to make sure all is kosher. That's what I call good service
Mind you, I've only had it happen once - that was with a damper that fractured a weld on a stone deflector about 10 years or so ago. Nothing hugely serious, but worth getting fixed none the less. All sorted in about 40 minutes from the point of driving in the door to driving out the door again. Can't be much happier than that...
Several good friends of mine in the Grey Army all use ARB gear exclusively for this very reason. One of them has had a couple of problems with the bullbar on his 200 series cruiser. First problems surfaced in central Aus. ARB head ofice in Melbourne authorised interim repairs (completed by some engineering place place in woop-woop) over the phone and arranged for the cost of the repairs to be electronically deposited that same day into their bank account. I think it was when they got to Adelaide, the bar was inspected and replaced. Done deal.
Sorry, slightly off topic, but with that kind of after sales support a company who supports their products like that will always get my money.
