In a 4x4 you have to upgrade front and rear diffs. PITA unless you know someone that does them. Z71s should have a 4.10:1 STOCK due to weight issues, if you have the extra cash or are spinning bigger tires... I&#39;d go for it. Consider even a 4.56:1 It&#39;s just 100rpm more on a 33" than a 31" on a 4.10:1.

But in a 2x4 I don&#39;t think there&#39;s enough difference to warrant the cost. I have 4.10:1 gears in my F150 now and I don&#39;t think I&#39;d do it again if I had the option. I&#39;d have just gone with the Eaton.

I&#39;ve had three Z71&#39;s (98,99,03) and they all had 3.73&#39;s for gears. Typically I see more 3/4 tons with 4.10 gears. [/b]

4.10:1s are only a &#036;50 option on Z71s, why mine didn&#39;t have that but it came with everything including Ride Control is beyond me.
