Complete piston ring set includes top compression rings, second compression rings, and three-piece oil control rings for reliable sealing and oil control. 🔧
Top compression rings are barrel face to improve heat transfer between the piston and cylinder wall and to enhance sealing under combustion.
Second compression rings feature a reverse torsional taper face to promote side sealing and prevent oil from being forced under the ring, improving oil economy.
Oil control rings are a three-piece Flex Vent design that provides uniform pressure through four steel rails and two expanders, assuring positive oil control and better conformability to the bore.
The reverse twist and taper-machined ring face duplicate the OD bottom-side scraping edge of a positive twist torsional ring for effective oil scraping.
Includes enough rings for two pistons (two rings per groove, except rails which use two rails per one expander).
Made in the USA. Please read the instructions furnished with the piston for correct top ring end gap and proper installation. 🇺🇸
