Upgrade your engine with the JE Pistons Piston Kit, designed for high-performance applications with a 4.320-inch bore and 4.500-inch stroke. Crafted from forged 2618-T6 aluminum, these pistons offer superior strength and durability, ensuring reliable operation even under demanding conditions. The forged construction promotes better grain flow alignment, which enhances overall tensile strength and resistance to fatigue, making these pistons ideal for racing or high-performance builds. The kit includes two pistons, premium ring packs, wrist pins, and wire locks, providing everything needed for a complete installation.

JE Pistons feature a skirt coating that reduces operating friction and wear, contributing to smoother engine operation and extended component life. Offset pins are incorporated to minimize piston rock and operating noise, resulting in quieter engine performance. Notched skirts allow for optimal clearance at bottom dead center, preventing piston-to-valve contact and ensuring consistent operation. An innovative accumulator groove below the top ring taps combustion gases, promoting a more effective seal and improved engine performance. Made in the USA, this piston kit combines quality craftsmanship with high-performance features to enhance your engine's efficiency and durability.
