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 through a reduced skirt width and a shorter wrist pin, which also contributes to saving weight on the piston assembly.

Are these pistons compatible with all LS7 engines?

This set is designed specifically for the LS7 engine and features a 4.130 inch bore. However, due to the specialized nature of performance engine builds, it's always recommended to confirm specific application compatibility with your engine builder or mechanic.

Product Details

Forged from 2618 aluminum, these JE Pistons STRKR pistons are built for serious performance in your LS7 engine. This set of eight is designed to handle the high stresses of demanding applications, offering a solid combination of strength and reduced weight. The specific dish/inverted dome design is tailored for the LS7, aiming to optimize combustion and power output for your specific build.

JE Pistons brings over 75 years of experience to the table with these pistons, which are forged and machined entirely in the USA. They feature a proprietary Forged Side Relief (FSR) design that helps cut down on friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight where it counts. Depending on the specific application, you might also find an accumulator groove to help manage combustion gas pressure, improving ring seal and keeping power consistent. Some applications also include a skirt coating to further reduce friction and wear on the cylinder walls, which can also lead to quieter operation.

This set is designed specifically for the LS7 engine, ensuring an optimized fit and performance. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a high-demand build, these pistons offer a well-built foundation for your engine's top end.
