What would be a smart route for me to take if I wanted to have better off-road capabilities from my JKU. I currently don't even have the limited slip differential. I understand that I can do as much as my pockets are willing to handle, so I'm looking for something modest. What would be the best option for installing a limited slip or lockers, and which parts are involved in this. This would be for an all around Jeep. Trails, Mud, Rocks (if I ever find some), Highway use since its a DD, and Mall Crawling when my wife has it.
