Have the bearings in the Metco Idler Pulley's 90/100mm been switched since they came out. Mine have the same oem bearings the stock pulley's have in them. I thought I read somewhere they switched to some BETTER high speed bearings.

Would like to know so I can get them switched out!

 

on JDM's site it says they now use some type of supercharger bearing.
Edit I dont think JDM's are metco
