Ok so I did the research and crunched the numbers and it makes much more sense to me to have a 4.56 gear ratio with a true 35 inch tire. I run the BFG mud terrains so they are pretty close. My normal Highway cruising speed is around 70MPH but most of my driving is under 40 around town. I am personally convinced I would get better fuel economy and a little lower crawl ratio off road. Also I am considering a lift and 37s down the road. Any thoughts on this or has anyone already made this upgrade? And which brand of gear would be best for the GM axles?
