Upgrade your high-performance engine with the JE Pistons Piston Kit, designed for precise 4.020-inch bore and 4.500-inch stroke applications. Constructed from durable 2618-T6 forged aluminum, these pistons offer superior grain flow alignment and increased tensile strength to withstand the rigors of demanding builds. The forged construction ensures enhanced durability, making them suitable for both street and racing engines. Each piston features a skirt coating that reduces operating friction and wear, contributing to smoother performance and extended engine life. Offset pins are incorporated to minimize piston rock and operating noise, ensuring quieter engine operation and improved reliability. The pistons include skirt notches for optimal clearance at bottom dead center, preventing interference during engine cycles. An accumulator groove is engineered to tap into combustion gases below the top ring, promoting a more consistent and positive ring seal for better compression and overall performance. This kit comes complete with two pistons, premium ring packs, wrist pins, and wire locks, providing everything needed for a comprehensive upgrade. Made in the USA, JE Pistons offers quality and precision for serious engine builders seeking maximum performance and durability.
