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

If you're building a high-performance 4.6L 4-valve engine, these JE Pistons STRKR piston set is a solid choice. Designed for the demands of racing and serious street performance, this set of eight pistons is built to handle significant power. They feature a 9.5:1 compression ratio, making them suitable for a wide range of performance builds, from naturally aspirated to forced induction applications.

JE Pistons has been a leader in forged racing pistons for over 75 years, and these are forged 100% in the USA from 2618 aluminum. This material offers the high tensile strength needed for high-demand performance applications. They incorporate JE's proprietary Forged Side Relief (FSR) forging design, which minimizes friction and power loss by reducing skirt width and using a shorter wrist pin for additional weight savings. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, improving ring seal and preventing ring flutter. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This set is specifically designed for the 4.6L 4-valve engine application, ensuring optimized performance and durability. Please note that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance use and are not intended for use in emissions-controlled vehicles in California.
