I own a 94 F-150 and want a L/S front diff. Are there any f-150s that came factory with L/S in the front. If so could the dealer tell from the VIN if a truck does have the L/S? I live next to a wreckers that deals mostly with Ford 4x4s so I have lots of trucks to look at for it.

 

I had one on my '90 F150 from the factory. Had to special-order it, tho.

 

Yes there are . I just bought a set out of rolled had dealer paper work in it from new . Had limited front and a auburn unit in rear (was a State government security Bronco) .

But I ordered the limited in all the trucks I bought new.

LOST

 

I installed a Dana Trac Lok L/S (and Powertrax no-slip in the rear) in the front of my 84 F150, it's a great combo. I paid just over $200 to my door from Bronco Graveyard.
