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 essential 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 legal for use in California?

No, this part is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

JE Pistons is known for its extensive experience in creating high-performance forged racing pistons. This set of eight pistons is specifically built for the 454 Big Block Chevrolet engine, featuring a .350 dome design. These pistons are engineered to offer a strong combination of durability and performance for demanding applications.

Crafted from 2618 aluminum, these pistons possess the high tensile strength necessary for engines pushed to their limits. JE Pistons uses a proprietary Forged Side Relief (FSR) forging 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 include an accumulator groove to help manage combustion gas pressure, which can improve ring seal and maintain consistent power. Some applications also feature a skirt coating designed to lower friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

Every component is forged and machined 100% in the USA, ensuring a high standard of manufacturing for these performance-oriented pistons. This set is designed for a 4.530 inch bore, with a 1.270 inch compression distance and a 0.990 inch wrist pin. Please note that this part is not CARB approved and cannot be shipped to California.
