guess lincoln locking it is out of the question ? i mean if your ditching the carrier when you do the selectable just weld it up right?? ..do you plan on going to a selectable ?.. Ive done mini spool for a buddy, welded diffs for a buncha buddies 8.8s, I'm actually running a really tight setup traclock in mine as a temporary till i can save for selectable but in all honesty i love it and it works good for the terrain, and im welded up front so maybe i dont notice any diffrence....that and so many other more pressing issues have come up on the jeep so moneys tight over here too.. not sure a lim slip would work for you if its mostly rocks you find yourself in, they work good in wet, snow, sand mud but serious crawlin will show how limited it is... just tossin out some food for thought.
