Cryo doesn't do much if anything

Since it says it has larger trunions, either it uses thinner caps, smaller bearings or no bearings.

None of which I'd trust in a rear driveshaft.  Front's only if you have lockout's. 

Spicer and the other major u-joint co's design theirs for maximum life (miles).  Pretty much anything from these small co's is going to give up life for strength.
