Baloney, if you CAN get the ARB.. DO get the ARB... those little lockers aren't really the answer.
Lot's of folks say the lockrites have done them well, and I am sure they have done OK.. but I bet those folks have never experienced a switchable locker.
The unpredictability of the lockrite type lockers makes them twitchy and noisey, and in my opinion unsafe and unfit for street driving, I have felt a jeep try to change lanes on the freeway suddenly with them.. yuk...
I wish someone would make a full size locker for these diffs like a detroit or something.. that would be cool and give another option, but for now, all we have are these half ass lockrites and ez-breakers..
Yeah, lot's of folks will swear by them.. but if I were you, I would DRIVE one with that type of locker before commiting. Don't let anyone tell you ARB's are 1300 delivered and installed, cause you can do it yourself, and power them with CO2 or compressed air if you don't want to buy the compressor.. there ARE other alternatives... I think you could get out of it for $800-850 an axle. and
ARB's are LIGHTYEARS ahead of those spider replacement type lockers..
