JE Pistons Piston Kit for 4.125 inch Bore and 4.50 inch Stroke with 12.0:1 Compression Ratio - Part Number 398762
Upgrade your high-performance engine with the JE Pistons Piston Kit, designed specifically for a 4.125 inch bore and 4.50 inch stroke. Crafted from durable 2618-T6 forged aluminum, these pistons offer superior grain flow alignment and increased tensile strength to withstand the demands of aggressive builds. The forged construction ensures longevity and resilience, making them suitable for both street and racing applications.
Each piston features a skirt coating that reduces operating friction and minimizes wear, enhancing overall engine efficiency and lifespan. Offset pins help reduce piston rock and operating noise, contributing to smoother engine operation. Strategically placed skirt notches provide optimal clearance at bottom dead center, preventing piston-to-wall contact during high-stress conditions. An accumulator groove channels combustion gases below the top ring, promoting a more consistent and positive ring seal for improved compression and power output.
The kit includes two pistons, premium ring packs, wrist pins, and wire locks, offering everything needed for a comprehensive installation. Made in the USA, these JE Pistons are engineered for durability and performance in demanding environments. Whether you're building a street machine or a race engine, this piston kit provides the reliability and high performance needed to maximize your engine's potential.
