My thoughs on the LSD is that it is not a locker and never will be. That said it's miles better than stock. I have one in my YJ. Whan I got my 8.8 I paid $25 more for the LSD and it already had 4.10's. When it comes time to rebuild, or if the day comes that I have $'s to burn I'll add a selectable locker, OX, ARB, etc. It works great on the road with was one of my reqirements. As you can see I have an OX installed up front. However, with even a stock setup by adding an 8.8 LSD even to a stock setup will greatly increase your offroad capibilities.
