Just my .02 worth, the 3.42 gears are a better all around gear ration for a truck. Especially if your tires are relatively tall. I get 19 to 20 on th ehighway with a 30.5" tall tire and running at 70 MPH+. The 3.08 gears, in my worlkd would take to much torque away from driving and truck usefulness.
