Upgrade your engine with the JE Pistons Piston Kit, designed for high-performance applications with a 4.080 inch bore and 4.500 inch stroke. Crafted from 2618-T6 forged aluminum, these pistons offer superior grain flow alignment and increased tensile strength, ensuring durability under demanding conditions. The forged construction enhances durability and performance, making them ideal for street, strip, or race engines. The skirt coating reduces operating friction and wear, improving efficiency and extending service life. Additionally, offset pins minimize piston rock and operating noise, while skirt notches provide optimal clearance at bottom dead center for smoother operation. An integral accumulator groove taps combustion gases below the top ring, promoting more consistent and positive ring seal for improved power output and efficiency. Each kit includes two pistons, premium ring packs, wrist pins, and wire locks, all manufactured in the USA for quality assurance. Whether building a high-performance street engine or a race motor, these pistons deliver reliable strength and enhanced sealing for maximum performance.
