Upgrade your high-performance engine with the JE Pistons Piston Kit, designed for precision and durability. Crafted from 2618-T6 forged aluminum, these pistons feature improved grain flow alignment and higher tensile strength, ensuring reliable performance even under demanding conditions. The forged construction provides enhanced strength, making these pistons suitable for both street and race applications. The kit includes two pistons, premium ring packs, wrist pins, and wire locks, offering a comprehensive solution for your engine rebuild or upgrade.
Built with advanced features, these pistons have a skirt coating to reduce operating friction and wear, contributing to longer lifespan and consistent performance. Offset pins are incorporated to minimize piston rock and operating noise, which helps maintain smooth engine operation. Notches on the skirt allow optimal clearance at bottom dead center, reducing the risk of contact and improving overall efficiency. An accumulator groove beneath the top ring captures combustion gases, promoting a more effective seal for improved power output and fuel efficiency. Made in the USA, these pistons meet high quality standards and are engineered for durability and performance.
Designed to fit a 4.075-inch bore and a 4.500-inch stroke with an 11.5:1 compression ratio, they are ideal for high-performance and racing engines. The kit's M8 hardware ensures secure assembly and reliable operation. Whether building a new engine or upgrading an existing one, this piston kit provides the quality and features necessary to achieve optimal engine performance and longevity.
