JE Pistons 4.6 3V MODULAR 11:1 Set of 8 Pistons

JE Pistons is known for making well-built forged racing pistons, with over 75 years of experience. They've applied that knowledge to this set of 8 pistons for the 4.6 3V Modular engine, designed for an 11:1 compression ratio. These aren't just off-the-shelf parts; they're engineered specifically for this engine and high-demand performance applications, aiming for the best mix of durability and power.

Forged in the USA from 2618 aluminum, these pistons have the strong tensile strength needed for serious builds. They feature JE's proprietary Forged Side Relief (FSR) design, which helps cut down on friction and power loss by using a shorter wrist pin and reduced skirt width, also saving weight. Depending on the specific application, you might also find an accumulator groove to help manage combustion gas pressure, which can reduce ring flutter and improve ring seal for more consistent power delivery. Some applications also include a skirt coating that works to reduce friction and wear on the piston skirts and cylinder walls, which can also lead to quieter operation.

This set includes 8 pistons, each with a 3.701-inch bore, a 1.220-inch compression distance, and an 0.866-inch pin. Keep in mind these pistons are not CARB approved and cannot be shipped to California. They are designed for performance builds and are made 100% in the USA.
