I have a 91 XLT that is basically stock but it's ALMOST paid for. Now I can afford to do some modifications. Most of my four wheeling is in the desert around Mono Lake or Death Valley or the Anza Borrego. We also go to Pismo and run the dunes once in a while. Anyway, I'm almost always in four low when I'm in four wheel drive, and I rarely get over 20 mph. So for low and slow, I'm thinking a true locker like a Detroit locker would be fine in the front. I want as much traction as I get. Any thoughts?
