Description:
JE Pistons oil ring expanders are available individually. They offer two different types. The F-type style expanders are most commonly used in low-tension oil rings and features a wave-shaped pattern that alternates between the top and bottom oil ring rails. The S-type style expander is more common in standard tension oil rings and uses holes in the humps to provide an oil passageway to the back side of the ring and ultimately out through the oil drain back holes.
