JE Pistons 4.6 4V MODULAR 9.5:1 Set of 8 Pistons

If you're building a high-performance 4.6L 4V Modular engine, this set of eight pistons from JE Pistons is a solid choice. These pistons are designed with a 9.5:1 compression ratio, making them suitable for a wide range of performance applications where you need a balance of power and pump gas compatibility. JE Pistons has been a leader in forged racing pistons for over 75 years, and they build 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 demands of a performance engine. JE Pistons also incorporates their proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width. This design, along with a potentially included accumulator groove and skirt coating (depending on the specific application), works to improve ring seal, reduce friction, and lower operating noise. Each piston is machined specifically for the 4.6L 4V Modular engine to optimize performance and durability.

This set includes eight pistons, each with a 3.622-inch bore, a 1.220-inch compression distance, and an 0.866-inch wrist pin. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are a significant upgrade for any serious engine build.
