Does anyone know of any manual hubs for a 2001 supercrew factory or aftermarket? If not then why aren't there any? Also, what kind of gas mileage would I get if I ran 33's with a 5.4? Thanks for all replies.

 

I don't know about the hubs, but I have Pro Comp 33 x 12.50 and I get 12 to 13. I almost got 14 one time but I came up a little short. I do pull a boat about 90 miles out of every tank. I have never had worse than 11.5 and that was with a boat the whole way. And I do tend to have a heavy foot. Hope this helps.

 

Your 01 doesn't have hubs. It has CV joints at the wheel. 4X4 is engaged at the differential.
