Product Details

JE Pistons has been a leader in forged racing pistons for over 75 years, building a reputation for performance and durability. This 400SBC ALLPRO/GB2000 piston set is a prime example of their commitment to high-demand applications. Forged and machined entirely in the USA from 2618 aluminum, these pistons offer the high tensile strength needed to withstand the rigors of performance engines.

This set includes eight pistons, each designed with a 4.140-inch bore and featuring JE Pistons' proprietary Forged Side Relief (FSR) forging design. This design helps minimize friction and power loss by reducing skirt width and utilizing a shorter wrist pin, which also saves weight. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, improving ring seal for consistent power, and a skirt coating to further reduce friction and wear while quieting operation.

These pistons are specifically designed for the 400 SBC engine and are intended for performance use. Please note that this set is not CARB approved and cannot be shipped to California. If you're building a high-performance engine and need pistons that are built tough and proven in racing, this JE Pistons set is a solid option.
