My concern would be drive shafts and U-joints we can only get up to a 1410 yoke for our axles if I remember correctly.
1410 is plenty stout. Even with my crazy tranny setup, I've still got the 1350 joint at the back of the zf and the front shaft is extra long ( my guy made it to max length spec for a single shaft and had to build it like a shaft for a semi to hold up against vibration to make it reach the Brownie in one piece. We did it that way with the understanding that if it vibrated like crazy , hed have to make it a 2 piece, but it worked perfeclty ) and it has a 1410 on it's other end then my short shaft between the Brownie and the diff has a 1550 at the Brownie and a 1350 at the diff and so far , it's holding up. Needless to say, I carry spare ujoints, but I haven't had to fool with them yet. When I go down into low range with a trailer on, the torque on things is beyond insane. It just pays to get good shafts built. I had my shafts built from scratch, I didn't have my stock ones modified, Aside from the fact that I wanted to be able to carry the stock ones with me in the event of Brownie failure, the purpose built shafts are much stronger than modified stock ones would have been. ( and had a price tag to match $$$ )
