The carrier is what matters...higher gears require a different carrier or a ring gear spacer...but wouldn't recommend spacers. The 8.2 housing will accomodate any gear.

I asked the question because some people misconstrue a locker as posi...but assumed you meant posi because nobody uses a Detroit locker on the street.

Determine what gear you want based on your driving style and go from there.

A high 2 low 3 gear will work with one carrier, and the 3..55-4.33 use another.
