I just have a few questions on the 2002 rear end. I have changed my gear to 3.73, I was wondering about the axles and the posi unit. What spline are the stock axles and how much can they hold. I have been told to just go with Moser 31 spline. Is this a good idea. Also while I am back there should I put a new posi unit in? Thanks for you help.

i believe stock is 28 spline. 31 spline moser is a great and common upgrade. im not sure how much power a stock rear end can hold but if your not running slicks i would think i would take a descent amount of power to shoot you rearend out even with et streets or drag radials
