Corvair Axle Ratios (Updated)

By Tim Palmer, Green Country Corvair Group

I have been ask many times what is the standard rear axle ratio for Corvairs. It is complicated. I have went through my Chevrolet Service News and The Corvair Decade to come up with the following chart that should help out. I did not use any sales literature because it is notorious for its errors, besides who believes sales anyway.
