Hastings has manufactured piston rings in the United States since 1915, supplying both the automotive and powersports rebuild markets. Rings are one of the few parts where a rebuild genuinely should not be cheapened.
When rebuilding a high-mileage V-twin, an overbore is often the best path to restoring compression and sealing. These Hastings Mfg cast piston rings are specifically designed for 1340cc Evolution and 1200cc Sportster engines that have been bored .020" oversize. Manufactured in the USA, they provide the quality and fitment you need for a lasting rebuild.
A proper piston ring seal is critical for both power and longevity. This Hastings Mfg piston ring set features a robust three-piece oil ring design, engineered to maintain consistent oil control and prevent blow-by in your Harley-Davidson engine. Each ring is crafted with precision to ensure an optimal fit within the newly bored cylinders, delivering the performance and reliability expected from a top-tier engine component.
Using the correct size piston rings is non-negotiable for a successful engine rebuild. These .020" oversize rings are intended for use with matching oversize pistons in cylinders that have been machined to the precise dimension. Whether you're refreshing a tired Evo or giving new life to a Sportster motor, Hastings Mfg provides the critical components to get your V-twin running strong again. Always confirm your bore size and piston type before ordering to ensure perfect compatibility and peak performance.

Would of rated it 5 star if I knew to get this set first rather waist money on the wrong set for my Keith Black pistons. Granted I should've researched it before I ordered the wrong set. Gotta make sure they fit BOTH pistons and cylinder size... Otherwise great product. Well packaged and each ring is labeled for correct fitment.
