Bore, 1.210 CD, Inverted Dome/Dish, 8 Cyl. Piston Kit JE designs are specifically engineered for extreme upplications up to, and including, professional competition

• Proprietary Forged Side Relief (FSR) forging design minimizes friction and power loss with reduced skirt width and saves additional weight with a shorter wrist pin
• Accumulator groove (depending on application) helps reduce pressure from combustion gases, reducing ring fluttering and improving ring seal for consistent power
• Skirt coating (depending on application) reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise
• Forged in the USA using 2618 aluminum, yielding high tensile strength needed for high-demand performance applications
• Designed specifically for each engine and use application to provide optimized performance durability
• Made 100% in the USA

The JE Pistons Gen 3 Hemi 6.4L Apache forged piston kit is engineered for high-performance Chrysler Mopar engines, featuring a 4.10-inch bore and a 1.210-inch compression height. Designed for demanding applications from racing to street performance, these pistons are crafted with precision to deliver superior durability and consistent power output. Manufactured in the USA using high-strength 2618 aluminum, they provide the necessary tensile strength to withstand extreme operating conditions. Each piston is specifically engineered for optimal fit and performance in Gen 3 Hemi engines, ensuring reliable operation during intense driving or racing scenarios.
JE Pistons incorporates advanced features to maximize efficiency and longevity. The proprietary Forged Side Relief (FSR) forging design minimizes friction and power loss by reducing skirt width and saving weight with a shorter wrist pin. The accumulator groove, depending on application, helps reduce pressure from combustion gases, which mitigates ring flutter and enhances ring seal for consistent power delivery. A skirt coating further reduces friction and wear on piston skirts and cylinder walls, while also lowering operating noise. These pistons are designed with a focus on performance, durability, and reliability, making them suitable for engines subjected to high stress and demanding conditions. Fully manufactured and assembled in the USA, JE Pistons offers a proven solution for racers and performance enthusiasts seeking high-quality forged pistons for their Mopar Gen 3 Hemi engines.
