Upgrade your high-performance engine with the JE Pistons Piston Kit, designed for precision and durability. Crafted with 2618-T6 forged construction, these pistons offer superior grain flow alignment and increased tensile strength, ensuring reliable performance under demanding conditions. The forged design enhances durability, making them ideal for both street and race applications. The piston kit includes two pistons, premium ring packs, wrist pins, and wire locks, providing everything needed for a comprehensive rebuild. Made in the USA, these pistons are engineered for quality and consistency.
The skirt coating reduces operating friction and wear, helping to extend piston life and maintain optimal engine performance. Offset pins are incorporated to minimize piston rock and operating noise, contributing to smoother engine operation. Skirt notches at bottom dead center improve clearance, preventing unwanted contact and optimizing movement within the cylinder. An accumulator groove taps combustion gases below the top ring, promoting a more consistent, positive ring seal that enhances power output and efficiency.
Designed specifically for a 4.080-inch bore and a 4.625-inch stroke, with an 11.5:1 compression ratio, these pistons are suitable for high-performance builds requiring reliable strength and precision. Whether upgrading for increased horsepower or rebuilding an existing engine, the JE Pistons Piston Kit offers a high-quality, engineered solution that meets professional standards and ensures long-lasting performance.
