JE Pistons 5.4 2V MODULAR 8.5:1 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 5.4 2V Modular engine, featuring an 8.5:1 compression ratio. These aren't just off-the-shelf parts; they're engineered specifically for performance applications, built to handle the demands of high-performance engines.

Forged in the USA from 2618 aluminum, these pistons offer the high tensile strength needed for serious builds. They incorporate JE's proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width. This design, along with a shorter wrist pin, also saves weight. Depending on the specific application, these pistons may also feature an accumulator groove to help reduce combustion gas pressure, improving ring seal and maintaining consistent power. Some applications also include a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise.

This set includes 8 pistons, each with a 3.572-inch bore and a -39.2cc dish volume, designed to achieve an 8.5:1 compression ratio. Please note that this part is not CARB approved and cannot be shipped to California. If you're building a high-performance 5.4 2V Modular engine, this set of pistons is a solid option for durability and performance.
