JE Pistons 4.6 4V MODULAR 11:1 Set of 8 Pistons

Forged from 2618 aluminum, these JE Pistons are built for high-demand performance applications. This set includes eight pistons designed specifically for the 4.6 4V Modular engine, featuring an 11:1 compression ratio. JE Pistons brings over 75 years of experience to their forged pistons, ensuring they are engineered and machined in the USA for the ultimate combination of durability and performance.

The proprietary Forged Side Relief (FSR) design is a notable feature, minimizing friction and power loss by using a reduced skirt width. This design also saves weight by employing a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, which can prevent ring flutter and improve ring seal for consistent power delivery. Additionally, a skirt coating, if included for this application, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This set is designed for a 3.572-inch bore with a 1.220-inch compression distance and uses a 0.866-inch pin. Because these are performance-oriented components, they are not CARB approved and cannot be shipped to California. For builders looking for a solid option for their high-performance 4.6 4V Modular engine, these JE Pistons offer a well-built solution with a focus on durability and optimized performance.
