you won't lose your over drive it just will not be as effective as if you had the stock 3.08 gears. The motor will be at a higher RMP while the truck is moving at a slower mph. In order to go the same speed as with the stock gears while cruising the motor will have to be at a higher RPM. Hrmmm.. ... hope that helped .
