Hell i don't know, it has black grease in it and the guy said they're meant for an M90, from my reading M62 and M90 are interchangeable.

I personally wouldn't use them unless I knew EXACTLY where they originally came from.

Why...? They're in a sealed package, prepackaged with the grease that'* meant for them.

How do you know it'* the grease that'* intended for this application if you don't know where they originally came from?

I don't think it'* that deep.

Seriously.

They're intended to be put in a supercharger, i'm sure he ordered them from one of the links you gave me.

I guess what willwren is trying to get at is if you install these bearings with the grease, and that grease breaks down due to it being improper for the application, you can, and will cause alot od damage to your supercharger, which, if you look it up, is a very exensive item to replace. The grease thats in there should be BLUE,and designed specifically for the Eaton supercharger, like willwren stated, this is VERY critical.

uhh, matt, both INTENSE'* website and the rollingperformance bearings i got have BLACK grease

I noticed it had a slightly blue hue to it. Whatever, it'* in there. :P
