what does it mean?
An F150 7700 series is an F-250 light duty. they changed the badges in 2001 i think. its got the 7700 GVWR, 4r100 tranny, 3.73 or 4.10 gears, thicker torsion bars and a bunch of other stuff.
I actually just picked up a 2001 7700. I will have to look in the owners manual tomorrow and see if it gives any specifics on all of the towing, gears and that good stuff, and I will post up anything if it says.





i want one.
