? on rear axle / locker

[NJH3]

I realize that the locker comes with the offroad package and I believe that the gear ratio is 4.56 with the pkg vs the 4.10 in the stock setup.

Can I order the rear locker and then pay to have the 4.10's installed on the carrier and set the ring and pinion back up? Or is the carrier that the locker uses only good for the 4.56's.

I'm comfortable with Dana 44's and Dana 60's and the carrier splits, setups, etc, but don't have a lot of knowledge on the Hummer's 10 Bolt.

Any help and or corrections would be appreciated.

And before anyone just asks why not get the package and be done with it, most of my wheeling is done in swamps and muddy trails vs. rock crawling, so I need the wheel spin and don't need the lower 4:1 T Case. Thanks.
