Tube step size

I was gonna say 5" if you get a lift.. But then again 4" is also good cause it gives you more clearance. Dunno if that matters much. But it's really what you want. I got 4" black mopar and really like them. Look kind of skinny side view tho.

Oops ya I have the 5" as well, same as Benny. Nice truck man, did u plastidip your rims black? I'm gonna do mine soon before winter comes.
