    O.K. did search.. found out pro's and con's between 14sf and 14ff.. I have a lead on a 14sf w/ 4.10's new seals and brakes for $200.00 I currently have a 12 bolt w/ 3.54.. want to go w/ 4.10 anyways... Should I jump on this or hold out for the 14ff.

    If you are sticking with the 33" or going no more than 37" in the future, then it's a good price for a regear and a little more beef.
    If you think you are like most where you will keep going bigger then hold off for a 14FF.

    I don't know about down there, but up here you can buy a 14bolt FF for 200 bucks all day long. I wouldn't waste my time w/ a SF for that kind of $$.

    I have no immediate plans to go bigger, however the TDS run end of this month might change my mind! /forums/images/graemlins/thumb.gif Right now its a daily and until I get another form of transportation it won't get radical yet... However I do really want to go to 4.10's...

    You need to figure in the price for regearing the front aswell. For me, I found it cheaper to buy a matched set of 3/4 ton axles. I got both front and rear axles (14 bolt FF rear / Dana 44 front ) with matching gears (From 78 3/4 Ton pick up.) for $250.00 total cost.

    [/ QUOTE ] If thats the case, maybe you'll get lucky and find something with a Dana 60 up front.

    The other half of the "?" is what are you going to do w/ the front? If its staying D44/10B then yes its a good idea. If you are going to use a D60 front then I would use a FF14B out back. Of course the usual tire size, usage, ect...

    Is wheel track an issue???
    --
    The FF is about 4-6" wider at the wheel fange than the SF
    --
    The FF is a 10.5 ring gear if I remember, and the other is 9.5..I may be wrong about that...
    --
    The FF is SIGNIFICANTLY heavier than the other...
    --
    The weight is all in the hubs, brake drums and spindles...something like 150 or 175 lbs..more...
    --
    More unsprung weight, crapy ride...
    --
    FF hub durms are hideously expensive..as are the brake shoes..
    --
    Just some things to consider /forums/images/graemlins/cool.gif /forums/images/graemlins/truck.gif
