I ran detroit in the rear and lockrite up front for YEARS, never had a single problem.. the lockrite would bind once in awhile and make a pop that sounded like the frontend just blew up but absolutely nothing wrong.

you might as well have a spool not to mention

You've obviously never actually ran a spool if you're trying to compare it to a detroit. As i've said once and i'll say again... I stand behind Detroits, they're strong and I have yet to see one break.. I abused the living SHIET out of mine and it never got close to giving an inch. I've seen a handful of ARB's blow up, or cut a line on the trail = worthless... or a compressor that goes out.. there's just to much crap to go wrong the more stuff that locker has to rely on to work the more you'll find yourself without a working locker!
