JE Pistons Gen 3 Hemi 6.4L Apache 4.095in Bore 4.1cc Dome 0.927in Pin Dia - Set of 8

If you're building a high-performance Gen 3 Hemi 6.4L Apache engine, getting the right pistons is crucial for durability and power. This set from JE Pistons is forged from 2618 aluminum, a strong material well-suited for the demands of performance builds. They're designed with a 4.095-inch bore and a 4.1cc dome, which helps achieve a specific compression ratio for your build. The 0.927-inch pin diameter is standard for many performance applications.

JE Pistons brings over 75 years of experience to these components, and they're made entirely in the USA. They feature a proprietary Forged Side Relief (FSR) design, which means the skirts are narrower and the wrist pin is shorter. This not only saves weight but also helps reduce friction and potential power loss. Depending on the specific application, these pistons might also include an accumulator groove to help manage combustion gas pressure, leading to better ring seal and consistent power delivery. Some applications also benefit from a skirt coating that further reduces friction and noise while minimizing wear on the piston skirts and cylinder walls.

This set includes eight pistons, enough for a complete V8 engine. They are specifically designed for the Gen 3 Hemi engine and its intended use, aiming for optimized performance and longevity. Keep in mind these are not CARB approved and cannot be shipped to California. For any high-output engine build, using pistons from a reputable manufacturer like JE Pistons is a solid choice for reliability and performance.
