What materials are these pistons made from?

These JE Pistons are forged from 2618 aluminum. This material is selected for its high tensile strength, which is necessary 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. It achieves this by reducing skirt width and utilizing a shorter wrist pin, which also contributes to saving weight.

Are these pistons compatible with all LS engines?

These pistons are designed specifically for LS engines and their intended use. It is recommended to consult the manufacturer's detailed specifications and your engine's requirements to ensure proper compatibility, as some features may vary by application.

Product Details

This product is a set of eight JE Pistons LS ASYM DM 4100STRKR pistons, designed for LS engines. You get the pistons themselves, ready for installation into your engine build. These pistons are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, making them well-suited for high-demand performance applications where durability is critical.

JE Pistons has applied over 75 years of experience to these forged pistons. They feature a proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin, saving additional weight. Depending on the specific application, these pistons may also include an accumulator groove to reduce pressure from combustion gases, which helps prevent ring fluttering and improves ring seal for consistent power. Some applications also feature a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, while also lowering operating noise. Each piston is designed specifically for the LS engine and its intended use, aiming for optimized performance and durability.

These pistons are made 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 assembly and compatibility with other engine components.
