Thanks for the input. Changing wheels and tires isn't really an option for me at this time. I have polished rims and good tires. I'm going to run it that way. As far as a gear ratio change. It's the cost of the ring and pinion and bearings/seals if required - I'll provide the labor.
What horsepower rating do you suggest? 430/430 or in that range? 370 is pretty light but it does have good "juice". I have to make a trip through the Rockies with it next week so that will tell the tale. I am hoping to get into Cummins and get the computer changed up this week if possible. I want to keep it in the torque range at Interstate speed. I just think if I do want to cruise at 70-75 mph sometimes, I don't want to have to twist the motor to 16-1700 rpm to do it.
I just did a routine check over on the truck today and felt a little too much play in the front bearings. This means a hub change because it's a unitized hub assembly. Priced an new hub today over $700. Ouch!!
