Upgrade your high-performance engine with the JE Pistons Piston Kit, designed for precision and durability. Featuring forged construction with 2618-T6 alloy, these pistons ensure better aligned grain flow and higher tensile strength to withstand the rigors of demanding builds. The advanced skirt coating reduces operating friction and wear, promoting longer piston life and smoother operation. Offset pins are incorporated to minimize piston rock and operate quietly, while skirt notches optimize clearance at bottom dead center for reliable movement and performance. An accumulator groove helps maintain an effective seal by tapping combustion gases below the top ring, resulting in more consistent power output and efficiency. This comprehensive kit includes two pistons, premium ring packs, wrist pins, and wire locks, providing everything needed for a professional installation. Made in the USA, these pistons are tailored for engines requiring a 4.075-inch bore, 4.625-inch stroke, and a 12.0:1 compression ratio, making them suitable for high-performance applications demanding strength and reliability.
