Our Summit® piston rings by Hastings are a steal at this price. They include Hastings Flex-Vent oil control rings to eliminate blowby, and cast-iron second groove rings with a reverse-twist taper face for reduced friction. The stock/street performance rings come with cast iron barrel-face top rings, while the street/bracket race rings have plasma-moly coated top rings.
