Replacement piston rings kit includes top compression rings, second compression rings, and oil control rings to restore sealing and oil control. 🔧

• Top compression rings are barrel face and cast coated to aid heat transfer between piston and cylinder wall.
• Second compression rings use a reverse torsional taper face to promote side sealing and improve oil economy.
• Oil control rings are a three-piece flex vent design with two expanders and four steel rails for uniform pressure and positive oil control.
• Reverse twist combined with a taper-machined ring face duplicates the OD bottom-side scraping edge of positive twist torsional rings.
• Includes enough rings for two pistons; two rings per groove except the rails where two rails accompany one expander.
• Made in the USA.

Kit includes:
• 2x Top compression rings
