How much HP does Spools rob? Just curious as to what the amount of horses a 9 inch Spool with 3.90 gears can possibly rob on auto? I guess it's a good sacarafice in the end though. No more breaking 10 bolts.

The spool itself will not rob any power, it is lighter than a stock diff case. The 9" will rob some power, maybe 10-15 over a 10 bolt depending on how you set it up. Some people will argue more though, which it has shown. Over a 12 bolt, the difference is going to be less.
