I have an 04 1500 2wd on a 6 inch lift and 35s. Looking to get a 3 inch body lift and 37s. I currently have 4.56 gears, and I was wondering if the change to 4.88 will be worth the price. Also would like to know mpg. Don't my know my exact mpg but it's daily driven and is filled up every 7-9 days depending on what I was doing that week. If I were to assume it'd be mid 14-15?
