So, i've got an '07 1500 Z71 classic. it's got the limited slip in the rear just like all the other silverados. i used to know more about them but my question is whether or not a guy can add more discs into the diff, in order to make it lock faster and harder. i believe in theory it works but has anyone done this? if it does work, it sure is a cheap and easy way to improve traction. thanks for your input!
