Until the tach redlines. The only problem you could have is tire wear if you do this on dry pavement. Or do very sharp turns at highspeeds. I have forgot the truck was in 4hi and done 75 on the highway. I only remember when I go to take a sharp turn and can feel the front diff. walking around the spider gears. I don't think you will be doing 75 on snowy roads.
