What material are these pistons made from and why is it important?

These pistons are forged from 2618 aluminum. This material is chosen for its high tensile strength, which is crucial for handling the extreme pressures and temperatures found in high-performance racing engines.

What is the Forged Side Relief (FSR) design?

The FSR design is a proprietary JE Pistons feature that helps minimize friction and power loss. It achieves this through a reduced skirt width and a shorter wrist pin, which also contributes to saving weight on the piston assembly.

Are these pistons compatible with all engine builds?

These pistons are designed for BBC (Big Block Chevrolet) engines. While they are engineered for high-demand performance, it's essential to verify that the specific bore size, dome volume, and pin diameter match your engine's requirements. They are not CARB approved and cannot be shipped to California.

Product Details

When you're building a high-performance big block Chevrolet engine for serious competition, the pistons are a critical component. This set of JE Pistons APBA Dome pistons is designed to handle the extreme demands of racing, whether you're on the dirt track or the drag strip. They are forged and machined entirely in the USA, using JE Pistons' extensive experience to create a part that balances durability with the performance you need to win.

These pistons are made from 2618 aluminum, a material chosen for its high tensile strength, which is essential for engines operating under high stress. JE Pistons incorporates their proprietary Forged Side Relief (FSR) design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, also saving weight. Depending on the specific application, these pistons may also feature an accumulator groove to manage combustion gas pressure, leading to better ring seal and consistent power delivery. A skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, contributing to a quieter engine operation.

This set includes eight pistons, each engineered specifically for the BBC application to optimize performance and durability. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a complete build, ensure you have all necessary supporting components and refer to the manufacturer's installation instructions for proper assembly.
