1)
Top Groove Hard Anodize (GC)
This coating has proven to increase power output by allowing for extremely tight
ring clearances. Available exclusively to top-level racing teams until now, this
top ring groove coating creates a hard mating surface which virtually eliminates
micro-welding while decreasing ring groove wear. Buildup is .00025" per surface
and clearance must be added during manufacturing to accommodate the change. |
 |
|
2)
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 .0003" to .0005" thick spray-on dry film that
will help reduce friction and inhibit galling. No manufacturing allowance is
required as this application is made to wear in to the cylinder wall. |
 |
|
3)
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. |

|
4)
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. |

5)
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 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. |
 |
|
6)
Anodize Option B (AB)
Offers twice the buildup of the standard process (.0005" per surface). Through
extensive R & D and field-testing, the Option B process has shown to be more
durable in maximum effort, high endurance applications. Appropriate
manufacturing allowances apply. |
 |
|
7)
Anodize Option C (AC)
This coating is the same material as the Anodize Option B except is applied to
the wrist pin bore instead of the top ring groove. This coating provides
increased lubricity, smoother oil transfer, and better wear in the pin bore. The
wrist pin hole must be honed both before and after anodizing. |
 |
|
8)
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. |
