What exactly with the axles? Shafts? Differentials? Isn't the "axle" is really just the means for housing these other parts?
I'm also thinking of going up to 35s. HD axle shafts and CV joints but stock gearing.
All of the above.
BTW. If stock gearing means stock open diff, then that will be what blows up next. It also means an already underpowered truck will feel even more so.
