I agree OEM is the way to go, but...since they are installed, I'm going to keep on rollin... I have had good luck with Timken in the past, but this is my first swap on a GMT900.Timkens are made in China. Pay the extra bucks and get OEM. I’ve tried every bearing, by far OEM is best choice. There is a Kryptonite Company giving lifetime warranty on bearings but they’re not cheap…
I did verify the QR code and they were authentic. Also, since the boxes didn't have the holographic security seal as I remember in years past, I called Timken to further verify and they said they don't use the sticker anymore, at least for my bearings.
