What material are these JE Pistons made from?

These pistons are forged from 2618 aluminum. This alloy is chosen for its high tensile strength, which is necessary for high-demand performance applications where engines are pushed hard.

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

The FSR design 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 in the piston assembly.

Are these pistons compatible with all engine builds?

These pistons are specifically designed for 350 and 400 cubic inch Small Block Chevy engines. They are not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

If you're building a high-performance 350 or 400 small-block Chevy, JE Pistons offers a set of forged dome pistons designed to handle the demands of serious engine work. These pistons are crafted from 2618 aluminum, a material known for its high tensile strength, making it well-suited for engines that push the limits.

JE Pistons has been in the game for over 75 years, and they build these pistons right here in the USA. They feature a proprietary Forged Side Relief (FSR) design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight in the process. Depending on the specific application, you might also find an accumulator groove to help manage combustion gas pressure, leading to better ring seal and consistent power. Some applications also include a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise.

This set is specifically designed for the 350/400 SBC engine, with a 4.155-inch bore and a 12.0 cc dome volume. Remember, these pistons are not CARB approved and cannot be shipped to California. They are sold as a set of 8.
