What are 14ff?

Just a quick low down, they are 3/4 ton and 1 ton rear ends for your vehicle. If you do a search for 14ff on here you will find a vast amount of knowledge on them. Im sure someone else will put up something more in depth than this but if you have more questions please ask. Good luck with you new journeys in K5's
GM's corporate rear axle that is of a full floating design .GM sold out to American Axle a while back so they are now referd to as AA 14 bolts.
There are two common 14 bolt axles that are discussed on this board , one is a semi-floater w/ a 9.5" ring gear diameter ( commonly found on 1981 and up light duty 3/4 ton trucks ) and the other is a full-floater with a 10.5" ring
gear diameter ( found on 1973 and up 3/4 & 1 Ton trucks ).

don't be afraid to search if you don't know something, if you can't find it or don't understand then post a question.

It is a 2wd 14 and because of the shims installed for pinion angle, the mount was too far forward to line up with the shock. This pic was just taken after the swap before the mount was moved...smart ass. /forums/images/graemlins/grin.gif

just a bit of trivia, everyone calls em a "GM/corprate" axle which is incorect. They are actually made by American Axle Manufacturing(AAM) /forums/images/graemlins/wink.gif
That said they the strongest reasonable axle you can get. Reasonable meaning they are fairly cheap and have good parts availibility.
They are the axle put under 3/4ton and 1ton trucks (single rear wheels). The FF is for Full floater whith means the axle is not connected to the hweel mounting surface as in a conventional axle. This resultes in a vary distictive hub on the rear axle. The biggest benifit of this is that if you break an axle shaft, your wheel and tire wont fall of.

Actually, you are incorrect. AAM is newer. 14FF are Corporate axles, made by General Motors.

Yeah, the sf and 10.5"ff are GM axles. The new AAM 14bff are 11.5" ring gear. I belive doge is starting to use them in the rear and front.
I believe that they are called "corporate axles" up until AAM purchased enough shares ( or however it was bought ) from GM to be on thier own .They are still made by the same company it just has a different name/owner and now they can sell to other manufacture's instead of being a division of GM .
