Those of you with 35+ Tires...
 

What does it take to fit 38's on an f150. Like, how big of a suspension lift or body lift? What is needed? I would like to know what to get beforehand. Any help would be appreciated!

At least 7" of total lift on a 4x4. To be safe you would probably want to do the 6" Fabtech suspension and 3" body lift.
With my 7" of total lift, I plan on going to 38s this spring with cranking the torsion bars and adding an extra leaf in the rear.
With a 4", 5", or 6" suspension lift combined with a body lift, one will also have to trim the valence which is not really a big deal.

Thanks sdiesel! That is what i was hoping to hear. I've currently got a 5.5" Superlift, and i'll add a 3" PA lift in the spring. That should be fine. I may need to crank the bars and trim some stuff - but that's cool.

You and I have very similar trucks, dude!
