I thought I had my finger on the Xterra aftermarket, but this is news to me despite being on the market for a few months.

TJM now has a Pro Locker air-operated locker on the market for both 1st-gen and 2nd-gen Xterras. Looks to be about $100 cheaper than the ARB, and may prove to be more reliable as the locking mechanism is external to the unit rather than internal. I dunno, but I'm intrigued.
