JE Pistons Gen 3 Hemi 6.2L Hellcat 4.09in Bore -4.8cc Dish 0.927in Pin Dia - Set of 8

This is a set of eight JE Pistons, designed for the Mopar Gen 3 Hemi 6.2L Hellcat engine. Each piston has a 4.090-inch bore and features an inverted dome/dish design with a -4.8cc volume. The wrist pin diameter is 0.927 inches. These pistons are constructed from 2618 aluminum, a material chosen for its high tensile strength, making them well-suited for high-demand performance applications where durability is critical.

JE Pistons brings over 75 years of experience to these forged pistons, which are engineered, forged, and machined entirely in the USA. They feature a proprietary Forged Side Relief (FSR) forging design that helps minimize friction and power loss by reducing skirt width. This design also saves weight by using a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, which can prevent ring flutter and improve ring seal for more consistent power. Some applications also feature a skirt coating designed to reduce friction and wear on the piston skirts and cylinder walls, while also lowering operating noise.

These pistons are specifically designed for the Gen 3 Hemi engine and its intended use, aiming for optimized performance and durability. 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 details.
