I selected the 4:10 axle ratio when ordering our new Unliited Sahara. We dropped by today with our trade and our salesman was double checking with me to make sure I wanted the 4:10 over the 3:21 because he was under the impression that jeeps with the 4:10 get approximately 25% less mpg then those with the 3:21's . for the most part, this jeep will be used on road with some light towing. It will go offroad from time to time but must likely through mud and light-med trails. It will not see any serious rock crawling or anything like that. I will, however be adding a lift and 35 or 36 inch tires in the future.
so, what mileage are you all getting with the two ratios on stock wranglers?

thanks for all the responses. We've decided to stay with the 4:10's. It just makes more sense. the missus is gone in to finalize the order and stuff today. I know it'll take a while for it to be built but i'm really looking forward to having our first Jeep! I'm also a little afraid that the aftermarket has really embraced the JK and that I'll spend waaaay to much on upgrades! It's a sickness I tell you! my truck is a great example! the longest I've left a vehicle stock is 1 week. I figure I'll have something added to this one befroe it comes away from the dealership!
thanks again!
