    ok my brother in law has a donco.he whats to upgrade the rear end.i told him he could probably put a 14 bolt back there,because there's no way he will break it.he replied no i'll keep it furd and put a 9inch and it will be just as strong and it's full floting so the wheel wont come off. i dont know much about a 9inch, but i dont believe its as strong as a 14bolt ff!hehe /forums/images/graemlins/thumb.gifwhat is your opinion

    many ford people go to the 14BFF because it is the stongest axle availible on the civie market, its cheap, and easy to upgrade (add a detroit and kick the piss out of it)

    Your BIL is full of crap. But mine is too so it must be a BIL requirement

    I don't think they made full floating 9 inch axles.

    i wasnt sure .so i quizzed! he says if the axle breaks its secure because the hubs are bolted to the tube.i told him im not sure which im not but i think it could be just the backing plate.but seeing how he knows it all i had to go with what he told me. i have not seen it.

    For weight savings, ease of gear change of strength all wrapped up into one, I'd go with 9 inch. The problems is the low pinion angle, spare parts are $$$$$ from what I am seeing and then of course setting it up for the vehicle, which he shouldn't have a problem since it's a Ford anyway.

    I'd take a 14B over a 9" any day. the only thing a 9" works in, IMHO is a race car.

    Plenty of race trucks surviving just fine on 9" inches.

    The 14ff is better but, with the options the aftermarket has for the 9" he could make it almost as stout as the 14ff. Dragracers have used these axles behind some seriously modified engines.

    show me what full size rigs are running 9"'s.

    There were 2 fords in this months FWOR running 14B's. Last years Tuff Truck champ was a F250 with a 14B.

    Ford was putting them in there 1/2 ton 4x4's. D44 front, 9" rear. A heck of a lot better than a 10bolt or 12 bolt GM.

    If its a stock 9in w/out some kind of FF kit, its a semi float. BUT they are a non C-clip type. The bearing is pressed on w/ a retainer to secure to the housing. The only place to brake a 9 and have the wheel fall right off is if it breaks outside the bearing.

    Buy a grand national(race not the GM car) stlye ford 9" It is a full floater, and has 5 on 5.5" bolt pattern. To keep a truck light a 9" is the way to go. Also there is every available locker, posi, and spool option out there. You can also get 40 spline alloy axles, which are bigger than 14 FF axles. The 40 spline shafts are 1.70" where a 14FF is 1.5" I was going to put one in my Jimmy brfore I got rid of it.

    Correct. We are ccomparing an axle put in cars and 1/2ton trucks to an axle put in 3/4 and 1tons. What I was saying is that it will not beat a 14ff. compared to what GM put in there cars and 1/2 tons it is alot better. /forums/images/graemlins/ignore.gif

    Well, here's just a few pics I dug up. All trucks are running a 9" inch, granted some of them are a "little" built up more than stock, but this shows the fact that the 9" due to it's design and strength out of the box has made it highly desirable for several facets of the off road community. Why do you think Currie offers all of those different versions? In fact, if I ever come across a housing, I have a third member setup with 4:11 gears and LSD that will see itself pulling Chevy duty.
    So you wanted pics, here ya go with commentary provided on some of them.

    Yeah, it's a Toyota and not fullsize, but who cares?
    [​IMG]
    [​IMG] Yeah, it's a Ranger, so what?

    As a side note, from the small number of races I've been to, most of the trucks had a 9" in the rear in some form or another; but the one and only truck I've seen with a 14FF grenaded one day. Just sheer luck, could be.

    For a application where weight is a priority, the 9 inch is perfect due to aftermarket support and design. Like I said, it does have a low pinion on it, but the pinion also has a second bearing, doesn't a 14FF have that also?
