So the question is how much stronger are 35spline cromo shafts in the rear compared to 30spline cromos?
If I went with 35spline would it be basically bulletproof on 37" tires?

so I have 07 x 2dr
I want to run 5:13 gears fully locked down the road....
For the rear axle what upgrades should be done?
As far as strengthening the rear shafts....what is need for 37's?
cro-mo stock replacements shafts (30 spline)?
32 spline (do they even make these for non rubi?)
or 35 splines?
if the consensus is go with cro-mo 35 splines....what ARB locker part# is needed to work with those shafts in my non rubi rear D44?

If you go with 30 spline, you can use your stock axles as spares, but 35 spline is "stronger"...
Basically though, after all the research and costs... it was the same amount of money for me to just buy a brand new G2 D60.
ARB 1000
Axles 500
Truss 300
Gears 400
Labor 1000
= 3200 (minimum)
Brand new G2 with ARB 35 spline axles and ARB and geared = 3500 and its much much stronger.
I did the same calculations with upgrading my D30... was going to cost to much, so I just went with a $5000 Prorock 44.

I am doing my own labor. So that makes it cheaper to just upgrade the non rubi rear D44....the D30 front is a lost cause so that one is being swaped for a complete aftermarket D44 axle.
