Im on the road so I cant do a actual break down , while the unproven zl1 diff is cheaper its not half as cheap as the aftermarket options.You will see some zl1 stuff break and the driveshaft will most likely start it off.The zl1 diff is no doubt an improvement over the stock ss but not in the same category as the hammerhead or 9 inch... If I can help you out with your drivetrain give me a call it may be cheaper than you think
