    Hey guys!

    Just wondering, is it possible to find a 6 lug 14 bolt semi floater that'll bolt into my 96 K1500? The stock diff is howling a bunch, and has a fair bit of excessive play in it... I'm tempted to put the beefier diff in instead of getting another 10 (12?) bolt diff to bolt in.

    If so, what does it take to change my front IFS gearbox to something with more like 3.73 gears? I did some checking, and it appears my truck has 2.73s...

    the new body style had 6 lug 14bSF. So its just a matter of searching local yards.

    The six lug 14sf is a bolt in deal for the 96 with exception of maybe the u joint. All the suff for the older trucks was 8 lug. Most just buy shafts, or they reweld perches for older trucks. Everything will line up on the 96 though.

    Sweet deal! I like the idea of a slightly beefier diff under my truck...

    Anyone have any input on gear ratio problems?

    Pretty sure that 4wd 1500's were available only with 3.42's or 3.73's in 96.

    Glove box RPO sticker should say GU6 for 3.42's and GT4 for 3.73's

    Hmm, maybe I just can't count, but one wheel rotation appeared to be about 2.75 driveshaft rotations, I'll check my glove box tommorow and see :D

    Hopefully they are 3.73!

    5 lug 14 bsf are in the 454 ss trucks, i think you can just swap in your 6 lug axels or get some alloy axels.

    True, but the 6 lugs are much more common than the 5 lugs. The 5 lugs also came in work trucks, but as far as the ss, I think everyone that has one wants to keep it.

    Your truck would have one if it had rpo F44.

    Make sure the one you find is from a 4x4, because the 2wd ones are narrower.

    Yup, used to work for a place with a fleet of the 88+ body style trucks, and at least 3 of them had the 14 bolt semifloater and were six lug. All of the trucks were K2500, but im guessing the 6 luggers are just a lower GVW.:confused:

    The method that I've found to work the best is to mark the sidewall of 1 tire and a u-joint cap and then jack up only 1 tire and have a friend spin that tire 20 times while you count the driveshaft revolutions. Divide the number of driveshaft turns by 10 for the gear ratio.

    This will work for an open differential or a gov-bomb.

    yup, just a lower GVWR. my uncle has a K2500 with a 14SF in it, and its 8 lug, but my C2500 (with a lower GVWR) has a 6 lug 14SF.

    I just read this thread , as I just got a 14bsf wrapped in a 93 k2500 .

    He can't put six lug 10 bolt axles into a 14bsf , 14bsf is 33 spline , not 30 like a 10 bolt :D

    But you can put six lug (from a light duty 3/4t) 14bsf in an 8 lug 14bsf (heavy duty 3/4t). :D

    But that mean someone most likely makes custom shafts and the brake stfuff is available:D or you could do it all with factory parts:D
