The ring is sized for pistons bored .040" larger than the original bore diameter. You must measure your piston to confirm this is the correct size.

Are these compression rings or oil rings?

This is a complete ring set with compression rings (moly-faced) and a three-piece oil ring design for Shovel engines.

Can I use these on a Twin Cam or Milwaukee-Eight?

Do I need a ring compressor tool for installation?
