I am an AVID offroader and have a pretty well set up rock crawler (1977 Chevy K5 Blazer on one tons, 40” tires, dual transfer cases, 4340 chromoly front axleshafts with 300M ujoints, powered by a 6. 0L LQ4 out of a 2005 Chevy 2500HD that runs on propane, list of mods goes on and on) and have had first hand experience with the eaton e locker. It’s a piece of junk. About 2 ½ years ago I ran one in the Dana 60 in the front of my K5 for less than a year and it broke. Granted I was pushing it pretty hard but it ended up being a design/manufacturing flaw that caused the failure. They were having a lot of problems with their early ones that they built and to the best of my knowledge have not corrected their issues. They at least stood up to the plate and refunded my money but I was still out the labor to install it and remove it. I ended up going with a Detroit locker up front just like in the rear. It’s locked 100% of the time but this rig doesn’t see any street driving at all so it’s no big deal. If you like, I have quite a few pictures of the broken locker and could send them to you.
IMHO if you want a selectable locker go with ARB. They are of superb quality, have a great reputation and stand behind their product. I’ve seen buddies of mine beat the hell out of their rigs and their ARB’s and haven’t seen one of them fail. You do have to worry about pinched/broken air lines and occasional compressor failures but those are easily fixed. I’d have no reservations about an ARB holding up in use in a CTD. Be prepared to spend some dough though…. to buy the locker, compressor, air lines and have it installed you’re looking at about $1300-$2000.
