🔧 Replacement piston ring kit restores sealing and oil control to improve combustion efficiency and reduce oil consumption.

• Includes top compression rings, second compression rings, and oil control rings.
• Top compression rings: barrel face, cast coated, and designed to help transfer heat between the piston and cylinder wall.
• Second compression rings: reverse torsional taper face that promotes side sealing and better oil economy.
• Reverse twist design with a taper-machined ring face duplicates the outer scraping edge of a positive twist torsional ring.
• Oil control rings: three-piece flex vent design provides uniform pressure through four steel rails and two expanders for positive oil control.
• Includes enough rings for two pistons; two rings per groove except for rail areas where two rails fit one expander.
• Made in the USA 🇺🇸
