I can get my hands on a set of used 3.73's out of a 2007 4.7 liter Commander. They are the factory mopar rear ring and pinion. This would work perfect for someone with a V6 looking to regear. There is a front diff in the for sale section right now with 3.73's. If you scooped both of these up you would have everything to regear. Looking for $150 plus shipping.
