I have 5203RS bearings in pulleys used in serpentine belt system on Z06-LS6 Corvette engine.
They are junk and have had to replace 8 in 20k miles!!
What quality are these and what can I replace them with that is best quality and last??
What is the Timken replacement or BCA or anyother you suggest that’s better.
I attached picture showing these pulleys that are billet made.
Thanks..
