Thanks Brian!! -----Original Message----- From: Brian Knight [mailto:[EMAIL PROTECTED] Sent: Sunday, December 04, 2005 8:46 PM To: [email protected] Subject: RE: [Chevelle-list] Ring and Pinion Auburn vs. Eaton
A 9" has a larger ring gear than a 12 bolt, 9" vs. 8.875, not much difference. The big advantage to the 9" is that you can change the ring and pinion as a single unit, making gear changes at the track or at home very simple. The 9" takes more power to turn than a 12 bolt (parasitic loss). They are great rears, but I would not put a F*** part under my Chevy!!! Curry or one of the aftermarket mfrs. now offers a 12 bolt with the quick change setup.
