12 bolt gear set treatment options

Racers,

with my Super 10 buildup it uses a 6.0 ratio 12 bolt. The truck will run low 10's at about 3100 pounds.

It has a 327/300/293 with powerglide and I will leave with trans brake.

My experience with a 12 bolt in other race cars is good, all giving excellent service life. However, never anything lower than a 5.13 ratio.

The pinion for a 6.0 ratio is mighty small, each time it look at it I shake my head.

Let me hear about your experience with gear treatment options
