DESCRIPTION
The piston rings include a moly-filled top ring with a
symmetric barrel face. The intermediate piston ring is
of the standard chrome design OR Micro-Napier
design. The Micro-Napier design has a reduced “hook”
on the running face, removes the need for chroming
and improves oil economy. The oil control package
consists of two steel rails and an expander spacer.
