I think it depends on which way you buy the axle. If you get the ones with inner cup included I've read that the inner cup and cv end are different then stock isuzu. If you get the ones without inner cup it should be the same as stock and fit the isuzu inner cup.

I've heard of cryogenicly treating cv's to increase the strength. I've never had it done and dont know how well it works. See if someone in your area does it and give it a try. If there isnt someone in your area you can try http://www.performancecryogenics.com/ but shipping might cost a bit.
