    Anyone know anything about this process? I figured i could get a used 14-bolt from a NBS 2500, and hopefully it would be a simple bolt in installation. What do you guys know about this process... Any info would be appreciated. :)

    I have done it several times, but not in the newer trucks. the only issue that I can think of that could be different, is possibly connections for the ABS. the driveshaft will need to be shortened a little unless the truck is lifted(14bolt full floater). you will need the spring plates and u-bolts from the 14 bolt, because the axle tubes are larger. the shocks and brake lines should hook up fine. be sure you get the correct ratio if its a 4x4.aside from that, it should be easy.

    If your talking about a 14 bolt ff, you will obviously need new wheels, or adapters, and have the hubs turned down by a machine shop.

    apparently the info im getting from fullsizechevy.com is that it would be best for me to get an OBS 14-bolt and weld up new spring perches. then do a rear brake swap to disc.

    :dunno:

    why?

    if it were my truck, i would get a rear that will bolt in. sure it will cost a little more, but it will be the correct width, probably have less mileage than an older rear, and will for the most part bolt right up. I could be wrong, but dont the 2001 3/4 and 1 tons have disc rears like the 1/2 tons do?

    Find a rear at a wrecking yard for your body style, and things will go smooth. you dont want to booger up a truck that new.

    10-bolt thats in there now is a POS. I already got it replaced once thru warranty, and now that I dont have that anymore, i have some plans for the truck.

    Adding a 6-inch suspension lift and 35s. the 10-bolt will NOT be able to handle those size tires and the abuse im gonna be putting it thru. Besides, its already starting to make some noises... AGAIN. :rant2:

    yeah... now im getting some new info. apparently one guy has a 14bolt full floater from an 02 3/4 ton truck, and all the measurements hes taken seems to be a direct bolt in. Now i just have to swap the rear to 6-lug and the u-joint. not too bad :hs:

    and yes, all 99+ trucks have disc rear, regardless of the size.

    yeah, well... it has 3.73s now stock. i havent done the lift yet or anything, and i know im going to have to upgrade, im looking at 4.56s for gears, maybe 4.10s, but probably the 4.56s in case i go with a bigger tire.

    i guess ill hold off on the swap and build up the 10-bolt for now. toss some gears and a locker in there or something. :dunno:

    10 bolts and 35"+ tires dont play well together, and thats a fact. it might work for your mall cruiser, but if you play off road even mildly, certain death.

    yea theres no way!
    as for the swap, go to a junkyard, find a 14bolt since they are probably everywhere, unbolt the 10 bolt and throw the other one on.. yea, the springs perches will need to be moved around etc, but u could do it easily in a day
    good luck
