I picked up a 95 Gmc k1500 a few months back. I have been trail riding with my friends a few times ant they think I should get a locker or spool. This is my first truck. I've got a free 3in body lift and am working on some 33's. So i'm not sure what to do. I looked at a quick lok but they salesman said it was loud and not ment for the street then tried to sell me a Limited slip. so what do you think, what do you guys use?
