I have a 99’ Chevy Tahoe which I put 33” tires on. I’ve been told that I should re-gear my axle so that I’m getting the best performance out of my engine but don’t know where to even start. I use my Tahoe as a daily driver and about once a month take the family either camping or some other outdoor event though any real four-wheeling is minimal. I was wondering if anyone can explain to me, in laymen’s terms, what I need to know. Or, if anyone has any suggestions or links to recourses, I would be greatly appreciative.

Thanks
