    Well, 5.13's is pretty far up there, but I think Summit has something for the 10 bolt around 5.50 /forums/images/graemlins/dunno.gif /forums/images/graemlins/yikes.gif

    I'd be weary of putting 5.13's in a 10 bolt because that most likely means two things. 1) you're running a rather large tire and your 10 bolt's not going to like that. 2) the torque multiplication of 5.13's is going to love eating axleshafts.

    The other problem with 5.13's in a 10 bolt is the pinion gear is getting real small and you become in danger of snapping your pinion under heavy torque or tearing off teeth because you don't have very many on the pinion with 5.13's.

    The carrier brake for the 10 bolt is 2.73 I believe.

    You'll need a new carrier. I currently run 3.08's and I am trying to switch to 3.73's. 3.73's are the limit on the stock 10b carrier. If I am wrong, will somebody please correct me?

    Your wrong from what I have been told. 10 bolts have the carrier break really low. 2.73 or 2.56. If you have 3.08s it should be the same carrier all the way up to 5.13.

    I am running 4.56's and I am pretty sure it is the stock carrier (bought the axle built already). When I was going to build my old 10 bolt I was going to go from 3.73's to 4.56's and I was told I wouldn't need a new carrier.

    For the D44 you would I believe. I know the carrier break for the 14bff is 4.10 and I believe that 4.10 is also the D60 break.

    I went from 3.73 to 4.56 in my stock 10 bolt (front) and they did not have to replace the carrier. They did for the rear though.

    Was your rear axle a govlock axle though? Did you replace the govlock with anything? If you went to a none full carrier traction device you would have to have a new carrier. In the rear you could install a detroit or other full carrier traction device and have that be the carrier.
