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.

What is the purpose of the Forged Side Relief (FSR) design?

The FSR design helps to minimize friction and power loss. It achieves this through a reduced skirt width and a shorter wrist pin, which also contributes to saving weight.

Are these pistons compatible with all Big Block Chevrolet engines?

These pistons are designed for Big Block Chevrolet engines with a 4.310-inch bore. While they are engineered for performance, it's always best to verify compatibility with your specific engine build and consult the manufacturer's detailed specifications.

Product Details

Forged from 2618 aluminum, these JE Pistons BBC pistons are built for high-demand performance applications. This set of eight is designed specifically for your Big Block Chevrolet engine, offering a robust combination of durability and power. The 4.310-inch bore size and .675-inch dome volume are key specifications for achieving optimal compression and performance in your build.

JE Pistons brings over 75 years of experience to the table, with these pistons being engineered, forged, and machined entirely in the USA. They feature a proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and utilizing a shorter wrist pin for weight savings. 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. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This set includes pistons for an 8-cylinder engine, with a 4.310-inch bore, 1.645-inch compression distance, and a 0.990-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance BBC engine, these pistons are a solid option for achieving your power goals.
