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 applications.

Are these pistons compatible with all LS7 engines?

These pistons are specifically designed for the LS7 engine with a 4.125 inch bore. It's always recommended to verify compatibility with your specific engine build and any modifications you may have.

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

The FSR design minimizes friction and power loss by reducing the piston skirt width. It also saves additional weight through a shorter wrist pin, contributing to overall engine efficiency.

Product Details

Forged from 2618 aluminum, these JE Pistons STRKR DISH/INVDM pistons are built for serious performance applications. They are designed specifically for the LS7 engine, offering a 4.125 inch bore with a -33.00 cc dish volume and a 0.927 inch pin diameter. This set includes eight pistons, ready to be installed in your high-demand build.

JE Pistons brings over 75 years of experience to their forged racing pistons. These are engineered, forged, and machined entirely in the USA, ensuring they meet the rigorous demands of performance engines. The proprietary Forged Side Relief (FSR) forging design is key here; it minimizes friction and power loss by reducing skirt width and saving weight with a shorter wrist pin. Depending on the specific application, these pistons may also feature an accumulator groove to help reduce combustion gas pressure, which improves ring seal and keeps power consistent. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation and longer life.

When you're building an engine for serious performance, whether for the dirt track or the drag strip, JE Pistons have a proven track record. This set is designed for optimized performance and durability, making them a solid choice for your LS7 build. Please note that these pistons are not CARB approved and cannot be shipped to California.
