I'm going to be ordering a JK soon and I'm trying to figure out if I need to order it with 3:73 gearing. Does anyone have a 3.6 Pentastar with 6 speed manual and 33 in tires and stock 3:21 gearing? Would it be better with the 3:73 gears? I don't plan on rock crawling, this is going to be a DD with occasional mild off roading in deep snow. I want the best gas mileage. I'm thinking with the 3:21 gears and the 33 in tires it will probably reduce the gearing to around 2:73 which should give me better gas mileage on the highway. If you have this setup please give me your opinion.
