JE Pistons 400 SBC .305 DOME Set of 8 Pistons

When you're rebuilding a high-performance 400 Small Block Chevy engine, you need pistons that can handle the stress. This set from JE Pistons includes eight forged pistons designed specifically for your 400 SBC application. They're made from 2618 aluminum, a strong material chosen for its high tensile strength, which is crucial for engines built for demanding performance use.

JE Pistons brings over 75 years of experience to these components, and they're forged and machined right here in the USA. You'll find features like their proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, saving weight in the process. 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. Some applications also feature a skirt coating that can reduce friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise.

This kit is designed for a 4.155-inch bore and features a .305-inch dome with a 10.8 cc volume, intended to optimize performance and durability for your specific engine build. Please note that these pistons are not CARB approved and cannot be shipped to California.
