They make them for the Dana 35 too. Had one in the rear of my XJ. I wouldn't recommend it for a daily driver though. Im going with an Aussie up front.Ive been researching these for awhile, all reviews of the product were excellent. These are only built for front Dana 30's, and would be horrible if placed in the rear since its an auto locker. The only problem i heard was annoying clicking when doing sharp turns, and are bad on snow/ice in 4wd.
