    The 14SF is substantially beefier than the 10-bolt so I would say it would hold up pretty well with 36's. You should still break the front 10-bolt well before the 14SF would ever let go.

    However, I personally think that $600 just for those axles is rather high. If they had some nice low gears or lockers than maybe, but if they were just something like 4.10's and open diffs than I wouldn't pay that much. Around here you can get the same setup for $200-$300.

    I would grab the 8 lug front and find a 14BFF with the matching gear ratio... The gov-loks are much better in the FF than the SF. I always think that if your going to 8 lug anyway than it isn't worth running the SF when the FF is just as easy to bolt up. I wouldn't pay more than say $400 or so for a 10B/D44 and a 14BFF with 4.10s and a gov-loked rear.

    ANY 3/4ton 14BFF that is out of an 87'-earlier GM vehicle will bolt up into your 85'. The emergency brake style is different on 70's 14FF's but any mid 80's 14FF will have the same style. DOn't sweat it... If you find a 14BFF out of a 3/4ton it will bolt in like it belongs there. The only parts you will need to make the swap is different u-bolts,plates, and a conversion u-joint. /forums/images/graemlins/thumb.gif

    Heck, if you are going through the trouble to go 8-lug, you might as well get the full-floater. They are more plentiful and much stonger.

    $600 for those axles is quite high. I picked up my 8-lug D44/14BFF combo for $150. Keep your eyes peeled and be patient, the right deal will come along. /forums/images/graemlins/thumb.gif

    i was under the impression that spring pads would need to be moved on 14b ff. is this true. would i be smart to get the 8 lug front from this truck and look for 14ff. he still wants 250 for the front, and one of the manual hubs is missing.

    Any 14BFF out of a 3/4 ton will work. The spring perches and shock mounts are in the correct locations. /forums/images/graemlins/thumb.gif

    $250 for a 10 bolt that is missing parts still seems high IMO. /forums/images/graemlins/thinking.gif

    The 14ff will bolt in. The manual hub is the same as your truck(if manual) is now. Where are you located? I have a 3/4 ton truck with 14sf. 150.00 would take both axels. I usually don't save semi floaters. Nobody ever wants them. I would usually get 250 up for a 10bolt/14ff set. Depending on actual conditions.

    600.00 is way too much. no more than 300.00 tops here for that. The last 14bolt ff I bought was 125.00 Save a little more money and get some real axles..........

    [/ QUOTE ] I think you'd be better to get both front and rear axles from the same truck (Matching gears) Look for axles from a K20. Sence you're in KC, call VANDER HAAG'S up in Co. Bluff's, Ia. (Just up I-29 a couple hours) (712) 323-9000 If all local searches fail.

    i wouldnt touch that junk for 600, thats crazy, id find a 14 bolt FF for 150 or less, they are dime a dozen and then wait on an 8 lug front axle or the parts needed from an 8 lugger to convert your front to 8 lugger

    cheap too, unless you go for dana 60 front

    42.5" spring spacing has been in use snce at least 1963 under 2wds all cept 1 ton so you can also use the 63-72 dana 60 rear FF axles too, most of them are 4.56 and 4.10 also
    rare few of them are 3.54 for the 396/402 engine for 3/4 ton

    The trouble is that most 3/4 ton trucks through the 80s came with the 14SF (despite popular belief on this board). When doing my 3/4 ton conversion several years ago I looked at a least twenty '83 or newer 3/4 ton trucks, 4x4 and 4x2, and none of them had a 14FF. The only 14FF I found were either in 1-tons or 3/4 tons from the 70's.

    At the time I was seriously considering getting the 14SF, but now I'm glad I got a 14FF to match the front Dana 60.

    WAAAYYYYY too much! /forums/images/graemlins/shocked.gif /forums/images/graemlins/eek.gif that 4.10 14BFF isn't hardly worth it's weight as scrap iron. Dozens of 14BFF's with 4.10's are around, and around here they collect and pile up in junkyards everywhere. I wouldn't pay more than 100 to 150 for one. I would pay a little more for one that had 4.56's but thats it. Guys on here have scored brand new military surplus 14BFF's with 4.56's and a true detroit locker for 400 to 500 bucks.
