JE Pistons 400 SBC DOME 18DEG Set of 8 Pistons

If you're building a high-performance 400 Small Block Chevy engine, a solid set of pistons is where you start. These JE Pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, which is exactly what you need when you're pushing an engine hard. They're designed specifically for the 400 SBC application, meaning they're built to handle the demands of racing and serious street performance.

JE Pistons brings over 75 years of experience to the table, and these pistons reflect that. They feature a proprietary Forged Side Relief (FSR) design that helps reduce friction and power loss by using a narrower skirt, and also saves weight with a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove to help manage combustion gas pressure, which improves ring seal for consistent power. Some applications also include a skirt coating to further reduce friction and wear on the cylinder walls, which can also help quiet down the engine operation.

Everything about these pistons is made in the USA, from the forging process to the final machining. This ensures a well-built component ready for your performance build. Keep in mind that these are not CARB approved and cannot be shipped to California. You'll also want to check the manufacturer's instructions for any specific installation requirements, as well as any other components you might need to complete your engine build, such as rings and bearings.
