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 essential for high-demand performance applications where engines are pushed hard.

What is the Forged Side Relief (FSR) design?

The FSR design is a proprietary forging from JE Pistons. It helps to minimize friction and power loss 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?

These pistons are specifically designed for the LS7 engine and feature a 4.128-inch bore. While they are made for the LS7, it's always recommended to confirm the exact specifications and compatibility with your specific engine build and other components.

Product Details

If you're building a high-performance LS7 engine, these JE Pistons STRKR DISH/INVDM pistons are a solid choice. JE Pistons has been making forged racing pistons for over 75 years, and they build these right here in the USA using 2618 aluminum. This material gives you the high tensile strength you need when you're pushing your engine hard, whether that's on the track or just for serious street performance.

What sets these apart is JE's proprietary Forged Side Relief (FSR) forging design. It helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, which also saves weight. Depending on the specific application, you might also find an accumulator groove to help control combustion gas pressure, leading to better ring seal and more consistent power. Some applications also include a skirt coating that cuts down on friction and wear, making your engine run quieter and last longer.

These pistons are made specifically for the LS7 engine, ensuring they're optimized for both performance and durability. They feature a 4.128-inch bore and an inverted dome/dish design with a volume of -33.00 cc. This set includes all 8 pistons, along with the necessary wrist pins. Keep in mind that these are not CARB approved and cannot be shipped to California.
