ARB hasn't dropped shipped lockers for several years or more, and we've stocked them for over 20. We get a weekely/bi-weekely truck order from ARB consisting of 2-4 pallets, lockers don't take up much space. When we ship you your new locker out it will include a personalized note from me
I'd stock the Harrop if there was genuine interest, as is now I've never had a single call for one, I'll have to ask Bryce if he has had any inquiries. I've seen them in Aus, talked to shops that deal with them over there, and read about them on Mud, etc but literally I've never had a single call for one. If/when they start hitting high trouble-free miles in Aus and the price reaches a point it competes and thus there is demand, I'd gladly offer them. We ran the Eaton D60 version when they were still pretty new on my partners rock-crawler in the 2005-06 timeframe when competitive crawling was all the rage. There were some issues and competitors are yet to go back to them to this day. The issue at the time was the stator spinning in the housing and thus ripping the wiring out. Along with that they took nearly 1/2 rotation of a tire to engage which was troublesome for rock-crawling though a non-issue for a 100 Series setup. I know the US Eaton applications have gone through a complete revision since that time and the engagement design was fixed and I can only assume the stator too. But without 100k mile users reporting it's really hard to say and like you I found some known failures at low miles though it's entirely impossible to know if those were install related.
Run em' your not going to get a personal note from me but perhaps you'll be my 100k mile user with good results
