BORE SIZE
JE offers your choice of bore size to suit your build. You have the option of stock bore sizing (82.5mm) or +.5m to +1mm oversized bores. Overbore pistons require additional machine work including a cylinder bore and hone. This work must be performed by a machine shop. For most performance engine builds, we recommend overboring the engine block when installing aftermarket pistons. This additional work ensures a proper piston to wall clearance and in most cases results in stronger compression, longer piston life, increased ring life, and quieter piston operation.

MANUFACTURING DETAILS
Forged from 2618 T6 aluminum
Engineered for extreme operating environments found in professional motorsport competition, JE manufactures this light yet strong piston from high tensile strength 2618 T6 aluminum. This high-performance alloy is suited for use with high compression ratios, high boost levels, and high octane usage tolerating acceleration forces of more than 8000 G's and directional changes exceeding 200 times a second while minimizing weight. This reliable forging is the ultra-high performance choice when building competition or very high powered boosted engine exceeding street power levels.
Optimized dish & dome design
The piston dish and dome have been individually designed to the combustion chamber of each individual application. Special care has been taken to provide properly placed valve reliefs as needed and feature smooth flowing radii across the surface for excellent flame travel. Designed and verified in JE's dedicated Critical Manufacturing Cell, providing reliable compression ratios and combustion characteristics.
JE Pro Seal piston rings
Every JE piston set includes a complete set of performance matching JE Pro Seal Piston Rings. JE Pro Seal rings are the result of over 60 years of experience in manufacturing racing piston technology such as NASCAR, ALMS, NHRA, and AMA. Pro Seal Ring features barrel-faced top rings made with premium ductile iron, plasma-moly inlays on the ring face combining nickel, chrome, and other trace elements. The second ring sets are taper-faced with a reverse torsional design and finished with a phosphate coating. These high-technology designs reduce friction, lower wear, improve ring seal, and extending ring life.
World class manufacturing and quality control
Meeting the extreme demands of today's ultra-performing race teams, JE Pistons are engineered, manufactured, and verified using during a Critical Process Program unique to JE. All critical surfaces are machined in a dedicated manufacturing cell resulting in tighter tolerances on 14 critical areas. 23-point quality inspection in an environmentally controlled lab maintained at a constant 68 degrees with 40% relative humidity. This ensures consistent and exact measurements and guarantees dimensional conformity. Each piston is serialized and tracked, you can rest assured your piston set is ready to use right out of the box!
