JE Pistons 4.6 4V MOD STRKR 11:1 Set of 8 Pistons

Forged from 2618 aluminum, these JE Pistons STRKR pistons are built for high-demand performance applications. They are designed specifically for the 4.6 4V MOD engine and feature an 11:1 compression ratio, making them a solid choice for serious engine builds where durability and optimized performance are key. Each piston measures 3.622 inches in bore diameter, with a 1.200-inch compression distance and a 0.866-inch wrist pin diameter.

JE Pistons brings over 75 years of experience to their forged racing pistons, and this set is no exception. They are engineered with a proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width. This design also saves weight with a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, which helps prevent ring flutter and improves ring seal for consistent power. Some applications also feature a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also cutting down on operating noise.

Every component in this set is forged and machined 100% in the USA, ensuring a high level of quality control and supporting domestic manufacturing. This commitment to domestic production, combined with advanced forging techniques, yields pistons with the high tensile strength needed for demanding performance builds. Please note that these pistons are not CARB approved and cannot be shipped to California. They are also subject to Prop 65 warnings.
