Default Auburn

Upgraded to the Auburn HP posi a few years ago and have no issue, even with my factory
3:08 gearing. Had an open factory carrier up to 72,000 miles. swapped to auburn posi and have been happy with it for 5,000 miles. yes I do not race or see any track time.
I have used factory auburn additive and Valvoline gear lube.
