OK, just wanted to post up what I have learned this year about the NAPA axles; Do not race with them!
I have certainly proved to myself that they can't take the holeshot abuse that the stockers can take. I went through 6 different Napa axles. I tried to ease out of the hole but to no avail. If you want to race, don't use the NAPA axles. If you want to tool around town and honk on it once in awhile, they should be fine.
My previous stockers lasted quite a while racing and daily driving (and these had 150k(ish) on them). But when they finally broke, I went to the NAPA's, but to no avail (both new and reman). I ended up swapping with a buddy of mine. I gave him the new NAPA axles and he gave me his 156k axles. They took at least 15 runs (with slicks) at the (cold) Shoot Out. No problems. And the last 2 runs were sit in the box and bounce of the rev limiter runs.
So I would say definitively, go with the high mile stockers instead of the NAPA's for race applications.
