X2, 4340 chromoly 27 spline shafts need to be in your short-term future.
Failures there are usually caused by the non-hardened OE axle shaft ears failing first which releases the u-joint to spin and bust up everything in its path. The world's strongest Dana 30 u-joint like a CTM can't prevent that kind of failure.
This shows mine, you can see where the ear broke when I was also at full turn-lock while giving a bit too much gas. We were doing some very low-speed rock crawling so things were quiet enough that everyone heard the 'TINK' as it failed. Had I been hammering the gas mine probably would have looked like Keg's.
