I ran 35s on my old 30 with stock shafts and a locker and my problems came from the rear axle. The ABS shafts are pretty strong and use the same u-joints as the 44. As with any front axle in a bind (wheels turned fully) under throttle you take a chance of snapping a shaft but the 30 is quite tough. I know tons of people with that set up or simular and seem to do fine. I say wheel it and if you do break down the road go for the chromos.
Axles, bit of lift and tars, what else do you need
What I lack in technique I make up for with skinny pedal.
Slightly "modified" Ford radius arms, 6" Rusty's TJ coils, RE 4.5" leaves, HD Offroad shackle relos, 2" shackle, D44 with chromos and a Spartan (welded), D60 Hobart locked with chromos, 38" TSL Bias on Eaton Beadlocks front and DIY beadlocks rear, partial cage, lots of rock love and a Warn for when I thought I could but was wrong.
