Just installed new ring &pinion, went from 3.73 to 4.56, I have 35"x18 tires &wheels, on a Ram2500HD 5.7 Heml, WOW With the tune from Hemifever and all the bolt ons. This truck is a BEAST, FOR you guys runing big tires &wheels with high gears, try a gear SWAP, loving truck all over again, even though it only has 4000 miles,
