i do not have a F150 yet, but i was looking at other trucks, and SUV's.. and some of them have an electronic locking differential, and super low 4x4 gear option, that will crawl over anything.. aka hummer

do any of the 2006/7 F150 models have locking differential or low transfer case gearing that can be selcted when in 4x4 mode?

 

No F-series truck was stock with a locker, or anything lower than a 3to1 in the transfer case's low range. Limited slip is available stock, or you can add lockers. Also it's not "too hard" to add a doubler between the tranny and xfer case if you wanna go crawlin.

Also remember that a Hummer is $100K+. That being said, there is no "ultra" low gear in a Hummer. The transfer case has a low range, as does the transfer case in F150.

And I'll put a stock Wrangler Rubicon against a stock H1 any day. The Rubi has electric lockers and 4:1 low range in the Tcase.
