What materials are these JE Pistons made from?

These pistons are forged from 2618 aluminum. This material is selected for its high tensile strength, which is crucial 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 by reducing the piston skirt width. It also utilizes a shorter wrist pin, which contributes to saving additional weight.

Are these pistons compatible with all LS7 engines?

These pistons are specifically designed for LS7 engines with a 4.125 inch bore. It is recommended to verify compatibility with your specific engine build and specifications before purchase.

Product Details

This is a set of eight JE Pistons, specifically designed for LS7 engines with a 4.125 inch bore. These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, making them well-suited for high-demand performance applications. They feature a dome design with a 3.20 cc volume and are made 100% in the USA.

JE Pistons incorporates several design elements for improved performance and durability. The proprietary Forged Side Relief (FSR) forging design helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin, which also saves weight. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, leading to better ring seal and consistent power. A skirt coating, also application-dependent, can further reduce friction and wear on the piston skirts and cylinder walls, while also helping to quiet down operating noise.

This piston set is engineered specifically for the LS7 engine and its intended use, aiming for an optimal balance of performance and durability. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For installation, refer to the manufacturer's instructions for specific details regarding pin fitment and assembly.
