What material are these JE Pistons made from?

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

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.

Are these pistons compatible with all LS7 engines?

This piston set is specifically designed for the LS7 engine. However, it is not CARB approved and cannot be shipped to California. Always confirm fitment details and consult manufacturer specifications for your specific build.

Product Details

Forged in the USA from 2618 aluminum, these JE Pistons are built for the high-demand performance needs of your LS7 engine. This set includes eight flat-top pistons, each designed with a 4.128-inch bore and a 1.115-inch compression distance. The 2618 aluminum alloy provides the high tensile strength necessary for serious performance applications, ensuring durability under stress.

JE Pistons incorporates its proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width. This design also saves weight with a shorter wrist pin. Depending on the specific application, these pistons may also feature an accumulator groove to reduce combustion gas pressure, preventing ring flutter and improving ring seal for consistent power delivery. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet operating noise.

This set is engineered specifically for the LS7 engine and its intended use, aiming for optimized performance and durability. It's important to note that this kit is not CARB approved and cannot be shipped to California. For optimal results, always refer to the manufacturer's installation instructions and recommended assembly procedures.
