You hear about the crank failures. The big end rod bearing.
Do they make a higher quality bearing replacement? I have a HR
stroker crank, it has lasted a year. Is there any difference in
bearing manufacters? Thanks.

did you get your HR crank assembly balanced to your piston assembly before installation?

Yes I did. But after further review, it was the crank bearing failure
that probably wrecked the big end rod bearing. Take a look.
