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 like racing engines.

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

Are any special tools or components needed for installation?

Installation of performance pistons typically requires specialized knowledge and tools. It is recommended to consult the manufacturer's installation instructions and consider professional installation for optimal results and engine longevity.

Product Details

Forged from 2618 aluminum, these JE Pistons LS ASYM FT pistons are built for high-demand performance applications. This set of eight is designed specifically for LS engines, offering a combination of durability and optimized performance. The 4.155-inch bore size and flat-top design with a -5.00 cc dish are key specifications for building a powerful engine.

JE Pistons incorporates its proprietary Forged Side Relief (FSR) forging design, which reduces skirt width and uses a shorter wrist pin. This not only saves weight but also helps minimize friction and power loss. Depending on the specific application, these pistons may also feature an accumulator groove to manage combustion gas pressure, leading to better ring seal and consistent power. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

Every component in this set is engineered, forged, and machined 100% in the USA, utilizing JE Pistons' extensive experience in racing piston manufacturing. This commitment to domestic production ensures a high level of quality control and material integrity, providing a solid foundation for your engine build. Please note that this kit is not CARB approved and cannot be shipped to California.
