HASTINGS Replacement Piston Rings — 3.000 in bore – 86-03 Sportster

Includes top compression rings, second compression rings, and oil control rings for complete piston sealing. ⚙️

Top compression rings feature a barrel face to improve ring-to-wall contact and support heat transfer between the piston and cylinder.

Second compression rings are Napier style; a reverse twist with a taper-machined face duplicates the outside-diameter bottom-side scraping edge of a positive twist torsional ring.

Oil control rings use a three-piece flex vent design and provide uniform pressure through four steel rails and two expanders for positive oil control.

The three-piece design allows rails with a small cross-sectional area for better conformability to the bore, promoting improved oil economy.

Promotes side sealing to help prevent oil from being forced under and behind the ring, reducing consumption.

Includes enough rings for two pistons, with two rings per groove except where rails use two rails per one expander.
