You can't do 3.08 in a 4x4. The numerically lowest ratio R&P set available for the front axle is 3.55. I haven't been able to find anyone who will custom hob hypoid gears. That is how sad our industrial base has become.

3.08s are only available for the rear axle.

A Gear Vendor or US Gear overdrive unit would give you a 2.98 ratio, but they are very salty and will tend to destroy automatic transmissions.
