What material are these JE Pistons made from?

These pistons are forged from 2618 aluminum. This material is selected for its high tensile strength, making it well-suited for high-performance and demanding engine 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 on the piston assembly.

Are these pistons compatible with all BBC engine builds?

This set is designed for BBC engines with a 4.500 inch bore and features a .600 inch dome. It's important to verify that these specifications align with your specific engine build and desired compression ratio. They are not CARB approved and cannot be shipped to California.

Product Details

JE Pistons is known for its forged racing pistons, bringing over 75 years of experience to domestic engine builds. This set of eight BBC pistons is forged and machined 100% in the USA using 2618 aluminum, a material chosen for its high tensile strength, which is crucial for high-demand performance applications. These pistons are specifically designed for BBC engines to offer an optimized combination of durability and performance, proven time and again in racing environments.

The proprietary Forged Side Relief (FSR) forging design is a key feature here. It helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, which also saves weight. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, reducing ring flutter and improving ring seal for more consistent power delivery. Some applications also feature a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This set is designed for a 4.500 inch bore and features a .600 inch dome. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a serious engine build where durability and performance are paramount, these JE Pistons offer a well-built solution.
