JE Pistons 400SBC ALLPRO/GB2000 Set of 8 Pistons

This is a set of eight JE Pistons, specifically the 400SBC ALLPRO/GB2000 model. These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, making them well-suited for high-demand performance applications. They are designed with a 4.125 inch bore, a 1.100 inch compression distance, and utilize a 0.927 inch wrist pin. This specific kit is intended for 8-cylinder engines.

JE Pistons brings over 75 years of experience to their forged piston designs, and these are no exception. They are engineered and machined entirely in the USA, ensuring a high level of manufacturing control. The pistons feature a proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin, also saving weight. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, which can improve ring seal and reduce ring flutter. Some applications also benefit from a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This set is designed for specific engine and use applications to optimize performance and durability. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance engine where durability and optimized power are critical, these JE Pistons are a solid option.
