I'm looking at possibly trading my current 10' Sahara for a used 19' sport. My question is the sport has a lift and 315/70/17 BFG's. It is spec'd in a 6 speed manual, with 3.45 gearing. My current 3.8 has the 4 speed auto trans with 3.73 and is kind of a dog with my current 285/75/17 Nittos. Does anyone have any input or experience with the current JL manual and this gear ratio/ tire size?
