Product Details
If you're rebuilding the top end of your LS engine for serious performance, a solid set of pistons is where you start. These JE Pistons are built for demanding applications, offering a strong foundation for boosted or high-compression builds. They're forged from 2618 aluminum, a material known for its high tensile strength, which is crucial when you're pushing an engine hard.
JE Pistons has been making performance parts for a long time, and they've put that experience into these specific LS pistons. They feature a proprietary Forged Side Relief (FSR) design that helps reduce friction and skirt wear, even with a shorter wrist pin. Depending on the exact application, you might also find an accumulator groove to help reduce combustion gas pressure, leading to better ring seal and consistent power. Some applications also include a skirt coating to further cut down on friction and noise. Every part of this set is made in the USA, ensuring they meet strict manufacturing standards.
This set includes eight pistons, each with a 4.075-inch bore and a -5cc dome volume, designed to work with a 0.927-inch pin diameter. Keep in mind these pistons are not CARB approved and cannot be shipped to California. For optimal performance and longevity, always refer to the manufacturer's installation instructions and recommended assembly details.
