Also, there is no way in hell CVs are going to hold up against 500hp and 37" tires. I'd say I'm fairly well committed at this point to the SAS.
While the stockers, or even my toyota ones wouldn't hold up to 500HP,
934.5 CVs CAN and DO take that HP and tire size!!!! the axle bars are 1.5" 35 slpine just like a dana 60!!! And they even have larger ones...series 50??? avail..... PRO 4 trucks use these....
