just like 4.0 said, you should still regear the axles down. With the 34's, freeway gears should be no less than 4.11's. I have 35's and am running 4.56's and i drive mine on the freeway everyday around 70-75 and get around 15 mpg.
I agree with the HP 44. The fact the pinion yoke is way out of the way is great. Plus, a stock exploder or Ranger front shaft will bolt right up.
