I'm considering upgrading to 410 gears from the 373's. I have 35'sfor tires. My question is what I can expect to pay? Also what will that do to my RPM's at highway speeds. A friend had a 2000 TJ and at 60 mph her tach was just over 3k.
How do you know what RPM to run if you want more power? Better towing? Better fuel efficiency. Find all the answers in this comprehensive gear ratio and tire size chart.
