Re: 12 bolt vs Dana 60
with the ratios of 5.86 - 6.14 the 12 bolt pinion is very small. It may have been an isolated case but with the 5.86 in my Super 10 it did not hold up. Even with a Cryo treated gear set. Installing a 5.57 gear gained one more tooth on the pinion and gear life was much better. This was with a SS 327 running 10.30s at 8400 - 8600 RPM at around 3250 pounds
