Upgrade your high-performance engine with the JE Pistons Piston Kit, designed for durability and precision. Crafted from 2618-T6 forged aluminum, these pistons feature aligned grain flow and high tensile strength to withstand the rigors of demanding applications. The robust construction ensures longevity and consistent performance under extreme conditions. The skirt coating minimizes operating friction and wear, promoting smoother operation and extended piston life. Offset pins are incorporated to reduce piston rock and operating noise, providing a quieter and more reliable engine. Skirt notches are engineered for optimal clearance at bottom dead center, enhancing piston movement and preventing contact issues. An accumulator groove beneath the top ring helps tap combustion gases, maintaining a positive and consistent ring seal for optimal combustion efficiency. This kit includes two pistons, premium ring packs, wrist pins, and wire locks, offering everything needed for a comprehensive rebuild. Made in the USA, these pistons are an excellent choice for high-performance and racing engines that demand quality and reliability.
