The JE Pistons 1/16-inch moly top piston ring for a 4.060-inch bore is specified for engine rebuilds requiring that bore diameter. As a moly-faced top ring, it supplies the wear characteristics associated with molybdenum-faced rings and is intended to be used in the top ring position for sealing and longevity in rebuilt or high-demand rotary cycles that match the 4.060" bore dimension.
