🔧 High-quality replacement piston rings designed to restore compression and control oil consumption.

• Includes top compression rings, second compression rings, and oil control rings.
• Top compression rings are barrel face and cast coated to aid heat transfer between the piston and cylinder wall.
• Second compression rings are reverse torsional taper face to promote side sealing and improved oil economy.
• Reverse twist ring with a taper-machined face duplicates the outer-diameter bottom-side scraping edge of a positive-twist torsional ring.
• Oil control rings are three-piece flex vent; the three-piece design allows rails to have a small cross section for better conformability to the bore.
• 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 the rails, which use two rail rings per one expander ring.
• Made in the USA.
