JE Pistons Gen 3 Hemi 6.4L Apache 4.10in Bore 1.210in Comp Height 0.927in Pin Dia Floating - Set 8

These JE Pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, making it well-suited for high-demand performance applications. They are specifically designed for the Mopar Gen 3 Hemi 6.4L Apache engine, featuring a 4.100-inch bore, a 1.210-inch compression distance, and a 0.927-inch pin diameter. This set includes eight pistons, ready for a complete engine build.

JE Pistons applies over 75 years of experience to their forged racing pistons, with this set being engineered, forged, and machined entirely in the USA. They incorporate a proprietary Forged Side Relief (FSR) design, which reduces skirt width to minimize friction and power loss while also saving weight. Depending on the specific application, these pistons may also feature an accumulator groove to help reduce combustion gas pressure, improving ring seal and consistent power delivery. Additionally, a skirt coating, if included for this application, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This piston set is intended for performance builds where durability and optimized power are critical. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
