JE Pistons 350 SBC .450 DOME Set of 8 Pistons

JE Pistons is known for making well-built forged racing pistons, bringing over 75 years of experience to domestic engine builds. This set of eight pistons is specifically made for the 350 Small Block Chevy engine, featuring a .450 dome to help achieve your desired compression ratio. They are engineered, forged, and machined entirely in the USA, ensuring you get a part built for serious performance and durability.

These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines operating under high demand. JE Pistons uses a proprietary Forged Side Relief (FSR) design, which reduces skirt width to minimize friction and power loss, while also saving weight. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, improving ring seal and preventing flutter. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This set is designed for a 4.030 inch bore and includes pistons with a 13.5 cc dome volume and a 0.927 inch pin diameter. While these pistons are built for performance, please note they are not CARB approved and cannot be shipped to California. They are sold as a set of 8.
