in my jk hp 30 i had 4.88 gears 27 spline chromo shafts good joints never broke a shaft or good joint. just shelled a lot of teeth off of the ring gear. this was with open diff. i dont see how i will be stuck with a 19 spline outer. i know i can get a 30 spline outer with the rcv's and a set of drive slugs or warn premium lockouts.
30 or 19 or even 100 ( ok a hunderd is a joke ) its still the same size Dia stub shaft, the spindle cant get bigger to allow a larger sized shaft threw it.
Thats my point, ftgiles and a few others in this thread is the stub will be the breaking point no matter what you run.
Thats what limits the 44, if you can address that some how ( witch i'm sure its been tried ) you could do all you talked about and have a killer axle to handle 38's.
The 60 allows you to run the 1.375" 30 spline stubs or the step up to the 1.5" 35 spline stubs, now you have a even flow of shaft and spline from flnage to flange.
In your case you will have 35 spline inners and 30 outers but the Dia will be greatly reduced in the stub, hence making a weak point.
Its not our money, just were trying to give advise to "not" follow down some of the paths we have taken.
This is why when we see the tire range you want now, we all said "well that where I want it to stop" and then when your tires are to small you think well I want to step up but question the axle.
With a 60 you have a golden ticket to take it to 46's.
Now heres the other question I ask, what about the rear axle. All this talk about the front and rear is overlooked. Dont say your thinking about the rear 60 from the same doner truck, please no.......................
