I figured the Vette crowd would've discussed this, but I can't find the answer to my question anywhere.
Looking at SKF hubs I see this statement:
"SKF manufactures the hub unit for the ultimate Corvette, the new ZR1 and is offering the same technology to the C5 and C6 owner."
My initial understanding was that the 33 spline ZR1 hub is made by SKF, and the SKF HD hub is basically the same hub offered in 30 spline to be a direct bolt on to all 30 spline Vettes without swapping CV shafts.
You can buy the SKF hub in both 30 and 33 spline for $350/ea. (There is a difference in ABS connectors for the different year Vettes)
GM lists two part numbers for 33 spline ZR1 hubs:
ACDelco RW20131 (25933291) 2009-2011. Rock auto has these for $300
ACDelco RW20145 (22804376) 2012-2013. Rock auto has these for $224
I'm trying to figure out if the ACDelco RW20145 is in fact the same as the 33 spline SKF HD hub.
A lot of us are running C5/C6 based sub frames, and at least one vender was offering C5 hub based "floater" axle ends. I'm building a chassis with C5 suspension front and rear, so saving $500 on a set of 4 hubs would be great. I'm going to need custom CV axles anyway, so using the 30 spline hubs won't save me money there.
Does anyone know if the AC Delco ZR1 hubs are the same as the SKF 33 spline hubs?
