I’d recommend taking a look at a Detroit Truetrac in the rear if you’re looking for something a bit more HD. I upgraded from the factory limited slip to one several years ago and have been happy. No discernible difference with normal daily driving, but the helical gear is a much more robust design compared to the clutches on the LS.
There’s been several threads on the subject around here, it really depends on what type of driving you do, you definitely do not want to run lockers when driving in snow or in icy conditions. For me, we often drive in mixed conditions, curvy mountain passes and in snow(not so much of that in Baja this winter though!) so running one of these Truetracs in the rear made the most sense, it doesn’t bind up when driving twisty passes or send your ass end swinging around when driving in snow like a locker would. If anything, I’ve considered putting a locker in the front and engaging that to help pull me out of being really stuck, but it would mostly only be useful in a straight line, try turning the wheel with a locked up front diff.....
