JE Pistons 4.165 400 SBC FT Set of 8 Pistons

If you're building a high-performance 400 Small Block Chevy engine, getting the right pistons is crucial for durability and power. These JE Pistons are forged from 2618 aluminum, a material known for its high tensile strength, making them well-suited for demanding performance applications where stock cast pistons just won't cut it. They are designed specifically for the 400 SBC engine, ensuring optimized performance and a solid foundation for your build.

JE Pistons brings over 75 years of experience to the table, and these pistons reflect that. They feature a proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by using a reduced skirt width. This design also contributes to weight savings, especially when paired with a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, leading to better ring seal and consistent power delivery. Some applications also feature a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet down engine noise.

Every part of this set is manufactured 100% in the USA, from the forging process to the final machining. This ensures a high level of quality control and supports domestic manufacturing. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're looking for a well-built, performance-oriented piston set for your 400 SBC build, these JE Pistons are a solid option.
