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 necessary for high-demand performance engine applications.

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

The FSR design minimizes friction and power loss by reducing skirt width and utilizing a shorter wrist pin. This also helps save weight on the piston assembly.

Are these pistons compatible with all LS7 engines?

This piston set is specifically designed for the LS7 engine. However, due to the custom nature of many performance builds, it's always a good idea to confirm the bore size and pin diameter match your specific engine requirements.

Product Details

If you're building a high-performance LS7 engine, you need pistons that can handle the stress and deliver consistent power. This set of eight dome pistons from JE Pistons is forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, making it ideal for demanding applications. JE Pistons brings over 75 years of experience to the table, engineering and machining these pistons entirely in the USA to ensure they meet the needs of serious engine builds.

These pistons feature JE Pistons' proprietary Forged Side Relief (FSR) design. This means they have a reduced skirt width and use a shorter wrist pin, which helps minimize friction and power loss while also saving weight. Depending on the specific application, you might also find an accumulator groove, which helps control combustion gas pressure to improve ring seal and maintain consistent power output. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation and longer life. Each piston is designed specifically for the LS7 engine to provide optimized performance and durability.

This kit includes everything needed for an 8-cylinder engine, featuring a 4.130-inch bore and a dome piston design with a 3.00 cc volume. The included wrist pin is 0.927 inches. Please note that these pistons are not CARB approved and cannot be shipped to California.
