JE Pistons 4.6 4V MODULAR 11:1 Set of 8 Pistons

This product gets you a complete set of eight JE Pistons, designed for 4.6 4V Modular engines with an 11:1 compression ratio. Each piston features a dome design, a 3.552-inch bore, and uses a 0.866-inch wrist pin. These pistons are forged in the USA using 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines built for high-demand performance applications.

JE Pistons brings over 75 years of experience to these components, applying their expertise to create pistons that balance durability and performance. They feature a proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin, saving weight. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, preventing ring flutter and improving ring seal for consistent power delivery. Additionally, a skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

These pistons are engineered and machined 100% in the USA, specifically for the 4.6 4V Modular engine and its intended use, aiming for optimized performance and durability. It's important to note that this set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
