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 to withstand the high demands of performance engines.

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

Are these pistons compatible with all LS7 engines?

This piston set is designed specifically for the LS7 engine. However, please note that they are not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

If you're building a high-performance LS7 engine, these JE Pistons DISH/INVDM pistons are a solid choice. They are designed specifically for the LS7 engine and are forged in the USA from 2618 aluminum, a material known for its high tensile strength, making them well-suited for demanding performance applications. This set includes eight pistons, each featuring a -30cc dish/inverted dome design, a 4.128-inch bore, and a 0.927-inch pin diameter.

JE Pistons brings over 75 years of experience to their forged piston designs. These pistons feature a proprietary Forged Side Relief (FSR) forging design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight. Depending on the specific application, they may also include an accumulator groove to help manage combustion gas pressure, improving ring seal and maintaining consistent power. A skirt coating, also application-dependent, can further reduce friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

When building a performance engine, the quality of internal components like pistons is critical. JE Pistons are engineered and machined entirely in the USA, ensuring a high level of manufacturing control. This set is designed for optimal performance and durability, making them a popular choice for those looking to get the most out of their LS7 engine, whether for track use or street performance.
