Greetings all, I have a 2011 Jeep JK Sport 6-speed standard. Needless to say it dies going overpasses or into the wind with the current 3:21 gears. I upgraded my wheels and tires to 33's on 17" XD Hoss wheels. I was told I needed to upgrade to differrent gears. I keep hearing 4:88's because I want to eventually run 35's but I think that's a little too steep unless the Sport is that much under powered. Any suggestions?
