I've got 33s on my JKU and the positraction rear-end. I'm thinking about an auto locker in back and will almost certainly leave the front end alone. I'm not planning on any real hard core rock climbing, but think the auto locker on the back would be a good and relatively inexpensive upgrade. Does anyone have any suggestions on which auto locker works the best in the JK? Is the positrac in the back going to make it harder to swap to the locker? One of the guys in our local club says he can help me install, but I've heard that the positrac makes working on the Dana 44 a little tricky.

 

love my detroit, does awesome on the trail and barely noticeable on the street

 

You currently have the factory Limited Slip in the rear? And not the factory e-locker, right?

Are you going to a 'lunchbox' auto-locker? (Aussie/LockRight/etc) Or a full case locker like the Detroit?

Lunchboxes are installed inside the factory case, so yes, that could be an issue if you have a limited. (I don't know how that would be handled, but maybe a new carrier, then setup the gears again, and install the lunchbox??)

A full case locker like the detroit will take the place of the carrier/factory limited, and you will need to set up the gears again. For the rear axle, this is a better option than a lunchbox, but also more expensive.

 

Detroit here also. Absolutley awesome offroad. Doesn't bother me at all on the street.

 

I'm also running the Detroit, and love it.

 

Yes it's the factory limited slip not the e-locker. From the posts so far, it looks like a detroit would be the way to go, but it doesn't sound like that would be a DIY project. The guy in the club built his own Grand Cherokee krawler so is pretty handy, but I should probably have my dealer do this job to keep the warranty valid. Thanks for the responses so far. Any additional thoughts?

 

You live in Idaho. First icy mountain road you go on you may wish you had chosen a selectable locker.

 

If they don't work well on icey roads that will definately be a deciding factor. Any other thoughts on this? I did call a 4x4 shop in SLC Utah that said they would install the Detroit in my rig for $1104 out the door. I thought that sounded reasonable. If I should go with a selectible locker which one should I get? About how much would that cost?

 

i also have a detroit in my jku i love it also runnin chrome-moly axles which i would recommend or just put in a tru-trac run old axles and have good snow/ice traction up to you
