What material are these pistons made from and why is it important?

These pistons are forged from 2618 aluminum. This material is chosen for its high tensile strength, which is crucial for handling the extreme pressures and temperatures found in high-performance and stroker engine builds.

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 reducing the width of the piston skirt and using a shorter wrist pin, which also contributes to saving weight.

Are any special coatings or grooves included with these pistons?

Depending on the specific application, these pistons may include an accumulator groove to help reduce combustion gas pressure and improve ring seal. Some applications also feature a skirt coating to reduce friction and wear, which can lower operating noise.

Product Details

This is a set of eight JE Pistons LS7 STROKER DOME pistons. 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 are designed specifically for the LS7 engine and stroker builds, aiming to optimize both performance and durability.

JE Pistons uses a proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width. This design also saves weight by using a shorter wrist pin. Depending on the specific application, these pistons may also feature an accumulator groove to help reduce combustion gas pressure, which can improve ring seal and reduce ring flutter for more consistent power. Some applications also include a skirt coating designed to reduce friction and wear on the piston skirts and cylinder walls, which can also help lower operating noise.

These pistons are manufactured 100% in the USA. Please note that this set is not CARB approved and cannot be shipped to California. It is important to consult the manufacturer's installation instructions for specific details regarding fitment and assembly, as these are specialized components for performance engine builds.
