    Hey, so i was just curious, what do ya'll think that a 14 bolt rear with disk breaks is worth? The axle is out of a 2004 Sierra 2500.

    How hard would it be to get the disk breaks hooked up and working back there? Would it be worth it over the drum breaks?


    Thanks fella's

    Not a 14 bolt is either an AAM 1050 or 1150. Don't think there is a locker available yet for it. I would pay according you your desire to have either an open diff or a gov loc as your only differential option. Plus they have the e-brake drum in the hat of the rotor which doesn't like mud at all.

    that would be the newer style 14 bolt, it may even be a 11.5 14 bolt im not sure when they changed over to mostly the 11.5's. but it should work fine for you its going to have a good setup becasue it will have parking brakes on it where most 14 bolt conversions do not, i would say pick the sucker up and use it

    the AAm 1050 is a standard GM 14 bolt and will fit the normal 14 bolt lockers, the 1150 is the larger version of the 14 bolt that is made to compete with the dana 80

    The last 1050 I saw didn't have a removable pinion support. Dunno for sure that it was a 1050, but I thought the 1150's only came in duramax trucks. This was in a long bed 2500 with a 6.0.

    the 1050 still has a removable pinnion support the 1150 does not, it was elimated becasue it made it cheaper to make, and my info comes directly form AAM, this summer im working at the plant that makes the 14 bolts

    I guess that i dont really care about the E-Brake because Its an auto anyways. It would be nice to have though, and if it was easy enough to set up then I would use it but other wise its kind of pointless to me.

    So I have another question. How weak is the stock 10 bolt? I am talking about the front one now by the way. I mean can you get axle shafts for them that are stronger or something? I mean I only have a 305 in my K5 and if I stuck with 37's would i be ok? I mean these freakin dana 60's are so damn expensive, it is throwing off my entire project. And its even worse that everybody knows exactly what they have, so I can never find any deals anywhere...anywhere close to me anyways.


    Thanks,
    Zach

    You'd probably be better off in the long run to find a "regular" 14 bolt and then swap to disc brakes if that is what you are after. A 10 bolt will let you down, especially with 37's. A 60 would be great, but a 10 bolt front *can* hold up if some sense is used.
