    hey.. I have an 81 K10.. I post ALL the time with questions because I am not intelligent to these vehicles yet... hence all the questions... anyway...
    I have a 14 bolt rear-end in my truck... is this stock?? Because I keep hearing you guys talk to me like a should have a 10 bolt back there... ITS NOT>.. it is huge.. 14 bolt.. looks stong... just rebuilt about 2 years ago and has nice clean synthetic fluids flying around inside. Is this because I have a K10... instead of a K5.. or because my truck has the towing package on it.. or because the guy before me was a genious????
    Also, what does this mean for my transfer case... same in a k5 as in a k10??? or tow package change this at all???? I know you guys have the answers... thanks

    the K10 and K5 have the same axles and t-cases and such. If your K10 has a 14ff in it, someone swapped it in.

    It has 14 bolts... and looks exactly like the picture... The front IS a 10 bolt though... I counted that one as well and it is MUCH smaller!! How well do these puppies hold up and do they make them for the front too, if so where do I get one?????? ( what kind of vehicle)

    <font color="green"> So are both axles 8 lug, or are they 6 lug, or are they mismatched? Good deal on the axle, but I'm sure you'll find something stupid that the PO did, we all have... /forums/images/icons/grin.gif </font color>

    NO, they are both 6 lug... front and back.. but I am not kidding.. it is definately a 14 bolt.. not like the 10 in the front.. not a 12 bolt either...
    It has been in the truck for at least 2 year.. .everything lines up straight and looks like it was done perfect.. doesnt make any funny noises either... all in all in great shape! I wondered why it looked so much cleaner and nicer than the front diff... /forums/images/icons/ooo.gif

    <font color="green"> I think you either have a 14b SF, which is still good, or you have a 14b FF that someone converted to 6 lug, which would be highly unusual. It's been done on here, but it would be odd to see one just out there randomly... Does it look like this -

    or this -

    <font color="green"> Yup, that's teh semi-floater 14 bolt, a light duty 3/4 ton axle. Still much better than a 10 bolt, and about the best axle you can easily get for 6 lug. The full floating version (the second one) is more or less teh strongest direct bolt in axle for Blazers, it came in 3/4 tons and 1 tons. </font color>

    if you thik that little 14 bolt SF loks huge wait til you lok under any 73-80 3/4 or 1 ton truck and see a 14 bolt FF, or even look under a 47-72 3/4 or 1 ton and see the h052 or h072 10 bolt corp rear end, or even a dana 70/80 axle in later trucks.

    the 14SF is only 1" larger than your front axle(8.5" vs. the 14 SF 9.5", but the the 14 FF is only 1" larger than the SF but loooks wayyyy larger)

    SF 14 was used under alot of 1@ and 3/4 tons i the 80's. very common axle in 6 and 8 bolt variety both. notice the very noticeable lack of the full floating hubs on your rear axle.


    good luck
