So i bought these not too long ago. Dude said they were aftermarket. It honestly doesn't matter to me, i just want to replace mine with torn boots. Either way im kind of curious to find out what they came out of. All axles that i have swapped before have looked the same except these.

Three things i noticed

1. the diff side to them are fully round. All others I've seen have that material removed in-between the bolt holes.
2. the hub side are also fully round, they dont have the dips to them like all the ones I've seen.
3. they are slightly beefier

 

no one?

 

can't really see the pics cause my awesome phone isn't very awesome, but they kinda look like 300zx axles... but don't quote me on that.

oh, and better luck posting in tech section instead of lounge
just sayin
