JE Pistons 4.6 2V MOD STRKR 8.5:1 Set of 8 Pistons

If you're building a high-performance 4.6L 2-valve modular engine, these JE Pistons STRKR series pistons are a solid choice. This set of eight pistons is designed with an 8.5:1 compression ratio, making them well-suited for boosted applications where you need to control detonation. JE Pistons has been a leader in forged racing pistons for over 75 years, and they engineer and machine these right here in the USA.

What sets these pistons apart is their construction and design features. They're forged from 2618 aluminum, a material known for its high tensile strength, which is crucial for handling the intense pressures in a performance engine. You'll find JE's proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and saving weight. Depending on the specific application, these pistons may also feature an accumulator groove to help reduce ring flutter and improve ring seal, and a skirt coating to further reduce friction and wear while also quieting down operation.

This set includes everything you need for an 8-cylinder engine, with a 3.572-inch bore and an 0.866-inch wrist pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For serious engine builds, especially those aiming for boosted performance, these JE Pistons offer a well-built foundation.
