Description:
JE Pistons Pro Steel piston rings utilize a high-strength, alloy-steel top ring that provides superior bore conformity. This is complemented by the outstanding seal and wear characteristics of a high-velocity, plasma-moly inlay coating. The top ring weighs under 10 g as a result of reduced ring radials and short axial heights, helping to minimize cylinder wall drag. The optional second ring’s Napier hook profile design helps to improve oil control and efficiency.
