JE Pistons Piston Kit - 4.320 Inch Bore, 4.500 Inch Stroke, 12.0:1 Compression Ratio, 114 Inch M8 - Part Number 399164
Upgrade your high-performance engine with the JE Pistons Piston Kit, designed for optimal durability and efficiency. Crafted from 2618-T6 forged aluminum, these pistons feature aligned grain flow that enhances tensile strength and structural integrity, allowing for reliable operation under demanding conditions. The forged construction ensures the pistons withstand extreme pressures and temperatures, making them ideal for racing and high-performance street applications. The kit includes two pistons, premium ring packs, wrist pins, and wire locks, providing everything needed for a complete installation.
Each piston is engineered with a skirt coating that reduces operating friction and wear, improving longevity and reducing maintenance needs. Offset pins are incorporated to minimize piston rock and operating noise, contributing to smoother engine performance. Notches on the skirt allow for optimal clearance at bottom dead center, preventing piston and valve interference. An accumulator groove taps into combustion gases below the top ring, promoting a more consistent and positive ring seal that enhances combustion efficiency and power output. Manufactured in the USA, this piston kit guarantees high quality and precision fitment for your engine upgrade.
Designed for engines with a 4.320-inch bore and a 4.500-inch stroke, these pistons have a compression ratio of 12.0:1, suitable for high compression builds. The 114-inch M8 hardware ensures secure mounting and compatibility with your engine's specifications. Whether you're building a performance street motor or a race-ready engine, the JE Pistons Piston Kit offers superior strength, reliability, and performance to meet your needs.
