Wow,just $2.15 to upgrade to a 4.10 </div></div>

Well, it's not an upgrade where they have to remove what is in there and replace it with 4.10's.

They just chose a 4.10 rear end from the parts bin. It's not any more expensive to manufacture that ratio. The extra cost is more because of a change from what is standard than a production cost.

Try and order an optional ratio today, and it's a big upcharge. Is that because it cost extra, or it screws with the corporate fuel mileage?
