One detail not mentioned, is current tire and/or future tire choice.

I would think an 8.75 would handle anything a 8.25 is currently handling.

There is one upgrade to the 8.75 I would suggest other then well assembled with quality R&P, are upgraded cap(S). a rear brace IMO does little to promote 8.75 member longevity, but it does stiffen the housing, which if that is an issue, you are already in Dana country.

Based on what you shared so far, my choice confidently would be the 8.75.

The key metrics here are IMO, car weight, engine torgue, transmission, tire package, future possible upgrades, and intended use. twocents


Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
