JE Pistons 4.6 4V MOD STRKR 9.5:1 Set of 8 Pistons

JE Pistons is known for making well-built forged racing pistons, drawing on over 75 years of experience. They've applied that knowledge to this set of 8 pistons, specifically designed for the 4.6 4V MOD engine with a 9.5:1 compression ratio. These pistons are built to handle the demands of high-performance applications, whether you're on the track or just pushing your engine hard.

Each piston is forged in the USA using 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines under heavy load. JE Pistons uses a proprietary Forged Side Relief (FSR) design. This helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, which also saves weight. Depending on the specific application, these pistons might also feature an accumulator groove to help manage combustion gas pressure, leading to better ring seal and consistent power. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet down engine noise.

This set is designed specifically for the 4.6 4V engine to give you optimized performance and durability. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are made 100% in the USA.
