JE Pistons 400SBC ALLPRO/GB2000 Set of 8 Pistons

This is a set of eight JE Pistons, specifically the 400SBC ALLPRO/GB2000 model, designed for 4.135-inch bore engines. These pistons are forged in the USA using 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines built for demanding performance applications. They feature a dome design and come with a 0.927-inch pin diameter and a 1.250-inch compression distance.

JE Pistons brings over 75 years of experience to these components, applying their expertise to create pistons optimized for both durability and performance. A notable feature is the proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width and utilizing a shorter wrist pin for additional weight savings. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, leading to better ring seal and consistent power delivery. Some applications also benefit from a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

These pistons are engineered and machined entirely in the USA, ensuring a high standard of manufacturing. They are designed specifically for each engine and use application, aiming for optimized performance and longevity. Please note that these pistons are not CARB approved and cannot be shipped to California. They are intended for high-performance builds where strength and reliability are paramount.
