HASTINGS Replacement Piston Rings — Set, moly-coated – 05-17 Sportster

Replacement piston rings kit designed to restore compression and oil control for worn cylinders. 🔧

Includes top compression rings, second compression rings, and three-piece oil control rings to ensure reliable sealing. 🛠️

Top compression rings are barrel face to improve sealing and aid heat transfer between the piston and cylinder wall.

Second compression rings are Napier style; a reverse twist ring with a taper-machined face duplicates the outside diameter scraping edge of a positive twist torsional ring, promoting side sealing and better oil economy.

Oil control rings are three-piece flex vent; the rails and expanders provide uniform pressure through four steel rails and two expanders for positive oil control.

Made in the USA and includes enough rings for two pistons; two rings per groove except where specified. Must order two sets for a complete motor.

Kit includes: 1x top compression ring, 1x second compression ring, 1x expansion ring, 2x rail rings. ⚙️
