What material are these JE Pistons made from?

These pistons are forged in the USA from 2618 aluminum. This material is chosen for its high tensile strength, which is necessary for high-demand performance applications.

What is the Forged Side Relief (FSR) design?

The FSR design is a proprietary feature from JE Pistons that helps minimize friction and power loss. It achieves this through a reduced skirt width and a shorter wrist pin, which also contributes to saving weight.

Are these pistons compatible with all 351 Windsor engines?

This specific set is designed for 351W SBF engines with a 4.040 inch bore. It's important to verify that this bore size and engine configuration match your build. Note that these are not CARB approved and cannot be shipped to California.

Product Details

If you're building a high-performance 351 Windsor engine, you need pistons that can handle the stress. This set of eight forged pistons from JE Pistons is designed specifically for demanding applications, offering the durability and performance needed to get the most out of your build. JE Pistons has been a leader in forged racing pistons for over 75 years, and this set reflects that experience, providing a solid foundation for your engine.

These pistons are forged in the USA from 2618 aluminum, a material known for its high tensile strength, making it ideal for high-demand performance engines. They feature JE Pistons' proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin, saving additional weight. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, improving ring seal and maintaining consistent power. Some applications also feature a skirt coating to reduce friction and wear on the piston skirts and cylinder walls, which also helps lower operating noise.

This set is designed for a 4.040 inch bore with a flat top and a -5.0cc dish. They include a 0.927 inch pin and a 1.280 inch compression distance. Please note that these pistons are not CARB approved and cannot be shipped to California. For serious engine builds, JE Pistons offers a well-built option proven in competition.
