you can, my friend had a jeep 2wd with like a 2 in lift and 31's with Lockers. With those lockers he could get thru some serious obstacles, i mean he did some pretty outrageous tings, especially for a 2wd jeep. Sadily, he rolled his truck doing donuts with the lockers engaged, apparentley u ar enot supposed to do donuts with lockers engaged.
