So I am not near my truck at the moment and but think I have the Tow package if not I have the 3.07 gearing. How will these fair in pushing 32's I imagine really bad but has anyone run it? Is there any way to bump them temporary to the Auto gears if I have a donor axle? I basically want to have the truck lifted by a certain time but don't think I will have money for the gears until after.
