Upgrade your high-performance engine with the JE Pistons Piston Kit, designed to deliver enhanced durability and superior performance. Crafted with 2618-T6 forged construction, these pistons feature aligned grain flow and increased tensile strength, ensuring reliable operation under demanding conditions. The forged design helps withstand the stresses of high horsepower builds, making them suitable for racing or aggressive street applications. The kit includes two pistons, premium ring packs, wrist pins, and wire locks, providing everything needed for a comprehensive installation.
JE Pistons incorporate advanced features such as skirt coating to reduce operating friction and wear, extending piston life and maintaining optimal engine efficiency. Offset pins minimize piston rock and operating noise, contributing to smoother engine operation. The pistons also feature skirt notches for optimal clearance at bottom dead center, preventing piston to wall contact during high RPM operation. An accumulator groove taps combustion gases below the top ring, promoting a more consistent and positive ring seal that enhances power output and reduces blow-by. Made in the USA, these pistons meet high manufacturing standards for quality and performance, making them ideal for custom builds and performance upgrades.
Designed to fit engines with a 3.937-inch bore and 4.375-inch stroke, these pistons have a compression ratio of 12.0:1, suitable for high compression applications. The included components and advanced features help ensure a reliable seal and efficient combustion, maximizing horsepower and torque.
