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 crucial for handling the stresses found in high-demand performance engine builds.

What is the Forged Side Relief (FSR) design?

The FSR design is a proprietary feature from JE Pistons that helps minimize friction and power loss. It achieves this by reducing the piston skirt width and utilizing a shorter wrist pin, which also contributes to saving weight.

Are these pistons compatible with all LS engines?

This specific set is designed for LS engines with a 4.000-inch bore and a flat-top piston configuration. It's important to verify your engine's bore size and piston type to ensure proper fitment. Additionally, these are not CARB approved and cannot be shipped to California.

Product Details

If you're building a high-performance LS engine, you need pistons that can handle the stress. This set of 8 ASYM FT 6098OEM pistons from JE Pistons is forged from 2618 aluminum, a material known for its high tensile strength, making it ideal for demanding performance applications. JE Pistons has been a leader in forged racing pistons for over 75 years, and these are engineered and machined 100% in the USA.

These pistons feature JE's proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width. They also use a shorter wrist pin to save additional weight. Depending on the specific application, you might find an accumulator groove to help reduce combustion gas pressure, which improves ring seal and prevents ring flutter for consistent power delivery. Some applications also include a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, leading to quieter operation and longer life.

This set is designed specifically for LS engines with a 4.000-inch bore and a flat-top piston design, featuring a -5.00cc dish. They have a 1.340-inch compression distance and a 0.945-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
