JE Pistons 4.155 400 SBC FT Set of 8 Pistons

JE Pistons is known for its extensive experience in forged racing pistons, with over 75 years in the industry. They apply this knowledge to their wide range of forged pistons for domestic engines. This specific set is designed for the 400 SBC engine, featuring a 4.155-inch bore and a flat top design. These pistons are engineered and manufactured entirely in the USA, using 2618 aluminum, which provides the high tensile strength necessary for demanding performance applications.

This set includes JE Pistons' proprietary Forged Side Relief (FSR) forging design. This design helps minimize friction and power loss by using a reduced skirt width, and it also saves weight with a shorter wrist pin. Depending on the specific application, these pistons may also feature an accumulator groove to help reduce combustion gas pressure, which can prevent ring flutter and improve ring seal for more consistent power delivery. Additionally, a skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, while also contributing to quieter operation.

When you're building a high-performance engine, especially for racing applications from dirt track to drag strip, JE Pistons have a proven track record of success. This set is made 100% in the USA and is designed specifically for the 400 SBC engine to offer an optimized balance of performance and durability. Please note that this part is not CARB approved and cannot be shipped to California.
