Im considering going with a gear vendors overdrive unit, when i get to that point on my K2500 with four speed. Since the gear vendor units are so expensive i might hold off for a while, but i think that is what i will use to make the truck more driver freindly at highway speeds. I also want to keep the truck as original looking as possible, with little to no mods, or i would consider going with the ranger gear splitter set up.
