I thought i had seen it here before but could be wrong so sorry if this has been answered already. Currenlty running 4.10's with ARB lockers and I want to regear to either 4.88's or 5.13's I do a lot of wheeling and moderate summer driving. So my question is, do I need to get new ARB's if I regear and which gears would you all recommend. Thanks...

Depends on your tire size primarily. And yes you should be able to use same ARB lockers.

 

Your locker is fine. With 37's and an Auto I'd say 5.13 is minimum for a 3.8L, some guys even like 5.38's with your set up. That depends on your driving style. I run 5.13's with 35's in a Manual, I love it but i'm running 3k RPM's at 70mph in 6th gear... Auto is much different though. In an auto with 5.38's and 37's you should be about 2400rpms at 70mph...

 

Very cool. Thanks for the info.
