Replacement piston ring set designed to restore sealing and oil control for worn engines. 🔧

Includes top compression rings, second compression rings, and three-piece oil control rings to manage lubrication and combustion gases.

Top compression rings are barrel face; second compression rings are Napier with a reverse twist and taper-machined face for improved scraping and side sealing.

Oil control rings are a three-piece flex vent design with two expanders and four steel rails to provide uniform pressure and positive oil control.

Promotes heat transfer between the piston and cylinder wall while preventing oil from being forced under the rings, improving oil economy.

Kit includes enough rings for two pistons: 2x top compression rings, 2x second compression rings, 2x expander rings, and 4x steel rails. 🇺🇸
