Thermal Barrier Crown (CC) The thermal barrier crown coating is 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.

Skirt Coating (SC) This is a "break-in" coating applied to the skirt of the piston only, designed to show wear. This coating is a spray-on dry film that will help reduce friction and inhibit galling during initial break-in. No manufacturing allowance is required as this application is made to wear in to the cylinder wall.

Tuff Skirt® (TS) Tuff Skirt® is a JE Pistons trademark coating that is a lubricating, anti-friction / anti-wear coating applied to the piston skirt only. Unlike our standard Skirt Coating, Tuff Skirt® wears slowly over time and is designed to withstand many different types of endurance applications including NASCAR, rally and off-road racing.

Oil Shed Coating (OS) This coating is applied to the underside of the piston. It is intended to reduce the reciprocating weight by repelling oil quicker than an untreated part. No additional manufacturing is required.

KoolKote (KK) KoolKote is an aerospace quality hard anodize applied to all surfaces of the piston with a buildup of .001". This coating is designed for use in nitro-methane engines such as Top Fuel Drag Racing to endure the corrosive effects of this fuel type. It will withstand greater temperatures and will not flake, chip or peel. This coating does alter the heat transfer and expansion characteristics of the piston. Consult the JE Pistons technical department for specific applications. Manufacturing allowances are required on all surfaces.
