What material are these JE Pistons made from?

These pistons are forged from 2618 aluminum. This material is chosen for its high tensile strength, which is necessary for high-demand performance applications.

Are these pistons compatible with all 427 BBF engines?

This set is designed for the 427 BBF engine with a 4.250-inch bore. It's important to confirm that these specifications match your specific engine build and requirements.

What is the Forged Side Relief (FSR) design?

The FSR design is a proprietary JE Pistons feature that minimizes friction and power loss by reducing the piston skirt width. It also contributes to weight savings by utilizing a shorter wrist pin.

Product Details

Forged from 2618 aluminum, these JE Pistons are built for high-demand performance applications. This set includes eight dome-style pistons designed specifically for the 427 BBF engine, featuring a 4.250-inch bore. JE Pistons brings over 75 years of experience to the table, engineering and machining these pistons entirely in the USA to ensure top-notch durability and performance for racing and high-output street use.

These pistons incorporate JE Pistons' proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width. This design also saves weight with a shorter wrist pin. Depending on the specific application, an accumulator groove can help reduce combustion gas pressure, preventing ring flutter and improving ring seal for consistent power delivery. Some applications also feature a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also contributing to quieter operation.

This set is designed for a 4.250-inch bore with a 1.670-inch compression distance and includes a 0.975-inch pin. Please note that these pistons are not CARB approved and cannot be shipped to California. They are made 100% in the USA, reflecting a commitment to quality manufacturing.
