JE Pistons 3.661in Bore 11:1 CR 1.4cc Dome Pistons Set of 8 for 2018+ Ford Coyote Gen 3

Engineered for precision and performance, these pistons are forged using high-quality 2618 aluminum, ensuring exceptional tensile strength suitable for demanding applications. The design is optimized for durability and efficiency, tailored specifically to meet the unique requirements of each engine application.

The proprietary Forged Side Relief (FSR) design minimizes friction and power loss, thanks to a reduced skirt width and a shorter wrist pin. This innovative construction not only enhances performance but also contributes to a lighter overall assembly. A specialized skirt coating (where applicable) further reduces friction and wear on both the piston skirts and cylinder walls, leading to quieter operation.

Additionally, the inclusion of an accumulator groove (when applicable) helps alleviate pressure from combustion gases, effectively reducing ring flutter and enhancing ring seal for consistent power delivery.

Key Features:

• Constructed from high-strength 2618 aluminum for superior durability.
• Proprietary FSR design minimizes friction and weight.
• Skirt coating (application-dependent) reduces wear and noise.
• Accumulator groove (application-dependent) improves ring seal consistency.
• Manufactured entirely in the USA for quality assurance.
