Common questions
What does ".020\" oversize" mean for this piston ring?
This ring is designed for 1340cc Shovelhead engine cylinders that have been bored .020" (twenty thousandths of an inch) larger than their original stock diameter. It will not fit stock bore or other oversize specifications.
Is this a complete set of rings for one piston?
No, this is a single piston ring. Engine rebuilds typically require multiple rings per piston (compression and oil rings). Please confirm the exact quantity and type needed for your specific build before ordering.
Will this ring fit other Harley-Davidson engine displacements?
No, this specific ring is engineered for 1340cc Shovelhead engines only. Using it on a different displacement, such as a 1200cc Shovelhead or a Milwaukee-Eight, will result in improper fit and engine damage.
