What material are these JE Pistons made from?

These pistons are forged in the USA from 2618 aluminum. This material is selected for its high tensile strength, which is necessary for high-demand performance applications.

What is the Forged Side Relief (FSR) design?

The FSR design is a proprietary forging from JE Pistons. It helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, which also saves weight.

Are these pistons compatible with all engines?

This set is specifically designed for BBC (Big Block Chevrolet) engines. While they are engineered for optimized performance and durability, it's important to verify compatibility with your specific engine build and application.

Product Details

This is a set of eight JE Pistons, designed for BBC (Big Block Chevrolet) engines. You get the pistons themselves, ready to be installed in your build. These pistons are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines that demand a lot of performance and durability.

JE Pistons has been around for a long time, and they've put that experience into these forged pistons. They use 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 your specific application, these pistons might also include an accumulator groove to help manage combustion gas pressure, leading to better ring seal and more consistent power. Some applications also feature a skirt coating that cuts down on friction and wear, which can also make the engine run a bit quieter.

Because these pistons are made specifically for each engine and use, they're optimized for performance and durability. Keep in mind that these are not CARB approved and cannot be shipped to California. They are also subject to Prop 65 warnings.
