Thanks for the tip Disco, searched their website but they don't list bilsteins for the Patrol. Every other make just about though :'(
Offtopic to your original question, but it would be worth dropping them an email if you're interested. Nissan don't sell the Patrol in the US, so that's probably why they're not listed. That said, as Bilstein dealers they can probably get whatever part you need, it'd just be a case of them looking in the book.
I've bought stuff from TruckSpring in the past, and they've been very helpful over email. One of the guys on the Pathfinder forum went back and forth with them, and eventually discovered that an airbag kit for a Kia Sorrento will fit a 2" lifted Pathfinder perfectly, so that's what I'm running in mine now. Nice people to deal with, who don't mind talking to you to find out what you need, vs just listing whatever's on their website. Shipping was fast and reasonably priced, what's not to like?
Good luck either way!
