JE Tuff Skirt Coating:
JE Pistons’ trademark coating that is a lubricating, anti-friction/anti-wear coating applied to the piston skirt only. Tuff Skirt will not wear and is designed to withstand many different types of endurance applications, similar to those commonly found in NASCAR. Buildup is .0005” per surface and finished diameter of skirt should include the coating buildup.
JE Thermal Barrier Crown Coating:
Applied to the top of the piston and is designed to reflect heat into the combustion chamber, thereby increasing exhaust gas velocity and greatly improving scavenging potential. The .0015” thick coating can also assist in extending piston life by decreasing the rate of thermal transfer.
