I was wondering... I have stock 10 bolts front and rear, and i was wondering how much of a beating they will take. They are open diff. and I will be running 33*12.50 tires. My new engine will be putting around 450 lb ft at the crank. If i get into low range, first gear, thats 3600 lb ft at the driveshafts! So does anyone have an idea of what these can take? I was thinking of goin to 35's later and superior axle shafts. I would like to keep the 10 bolts just to keep wieght down. opinions please!
