Welcome to JeepForum, you've just found one of the best jeep sites anywhere!

Cons tend to be the expense and the noise they make in the corners. It doesn't bother me tho.
Pros is that lockers make the jeep nearly unstoppable, I regularly drive thru blizzards and ice and
the trucks I have had with lockers can keep up with snowmobiles and ATV's when the going gets rough.

You might want to seriously consider upgrading your rear axle before putting a locker in the back - the Dana 35 is known to be weak and failure-prone even in stock condition on the street. Most guys put at least a Ford 8.8 out of a Explorer for a rear axle, then they upgrade that with the lockers etc. Hope this helps!

^^^ couldn't have said it better myself however I'm in the parts gathering process for my 8.8 and d30. I'm going with yukon grizzly lockers. About $60 less and higher quality and they stand behind their product more then Detroit who's quality has gone down over the past few years but they still make a great locker.

Gotta watch Detroit, they don't stand behind their products. I have newish true tracks front and rear and the axle splines stripped out on the rear drivers side in my driveway in 6" of snow. Detroit (Eaton) flat out refuses to sell me the part saying only "the true track is not repairable".
The metal is supposed to soo hard, yet the axle stripped out the splines.... Junk.

if you live in a snow region, You should go selectable in the front. Selectable rear if you can afford it. You dont want to drive on ice and snow on the roadways with an auto locker.

That's true, you can just be super careful. Still shouldn't be recommended though.

Been doing it for well over 10 years every winter. I prefer the predictable locked rear that will climb snow covered hills to an open rear that wouldn't get half way up up the hill. A front axle is best to be selectable in the snow the rear is better locked IMO. I've never said "oh man I wish I had a selectable rear."

I've also found their customer service useless and they will not sell parts of any locker except a certain parts of a dana 60.

I dont think I would like a detroit on a stock wheelbase rig that was driven daily. They like to pop and lock/unlock alot

Had one in a rear axle in a Toyota and it would eat tires.

I had one in my third dana 35. 4.10 with 31's made me want to pull out my own teeth on the road. When I threw on 35's I felt a lot better about it!!

There is a whole thread right on top of YJ Tech section. Basically get an 8.8 out of Explorer, Mountaineer. Try '97-01 get the rear disks. Buy a bunch of cut off wheels. M.O.R.E you can get spring perches, shock mounts and parking brake cables to make it all happen. Welding required

Or punt on all the work and call East Coast Gear Supply if you are willing to show out the extra cash. They'll put whatever you want into a remanufactured Ford 8.8.
