Have a 2019 sport 6 speed manual. Looking to regear as it sucks on 34’s (305/70/17). You really gotta search for power and do a lot of downshifting. It has a 3.5” rough country lifts well. It goes off road but not too much. Main desire to regear is for on road use. 4.56 or 4.88? And what manufacturer?? The Jeep is my wife’s. I have a Toyota... so I’m new to Jeeps.
