Piston Rings Bore 3,895" (98,933 mm ) Compression rings: 4 - 1.5MM, oil segment: 2 - 2.5MM +.020 mm Moly 1690 ccm (103 cui)

Description

These ring sets are manufactured by Hastings and are the ideal combination of design and materials that work together as a team, delivering full power and lasting oil and blow-by control. All ring faces are pre-lapped for easier seating, and in the moly sets, the compression ring features a moly insert on its barrel face design. The exclusive Flex-Vent oil control ring is the easiest of all designs to install because there are no right sides up or sides down. It can’t overlap, can’t gouge and can’t be installed wrong. The 80-plus shoulders on the die-formed stainless-steel stress relieved spacer-expander exerts uniform pressure on the rails assuring positive oil control, and with its open design affords 200% greater drainage capacity than conventional designs.

All Hastings Piston Rings are sold in pairs for two pistons with the exception of the rings for Evolution Sportster models, which are sold in single cylinder sets only.
