Hey guys, I have an 2005 H2 SUT. i will be putting a locker up front and while i am at it i want to do a gear swap. What gear would you guy recommend? 4.10s come stock. I was thinking 4.56 or 4.88. My Hummer is a DD in the winter time, and hopefully i will be able to hit the trail for the first this spring. It has a 20in wheels that wrapped in a 275-65 tire. Thanks
