At the end of the day with modern manufacturing processes every bearing from every company is damn near identical in performance. I would comfortably use any of the big 3's (ACL, King, Clevite) race bearings interchangeably, it's all personal preference.

Thanks for explaining all that lol, been a while since I've shopped for bearings, I remember now that Calico'd Clevites were his preference.

In regards to Calico and WPC, I assume if one was planning to get their bearings of choice WPC treated, then there would be no gains from having them Calico coated before the WPC treatment? Even though WPC says they can treat wear coatings as well and that it's more beneficial than non-treated coatings.


I haven't actually had parts WPC'd yet but it's super appealing, would love to do a new build with WPC on every internal part haha.

Hmmm that's some internet science that's a bit over my head to be honest, thinking about multiple treatments and coatings and how they interact with each other hurts my head.
