JE Pistons 400 SBC DOME -12 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. This set from JE Pistons is designed for those demanding builds, offering the strength and durability needed to handle serious power. They're forged from 2618 aluminum, a material known for its high tensile strength, making it well-suited for engines pushed to their limits.

JE Pistons brings over 75 years of experience to these components, and they're made entirely 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, improving ring seal and keeping power consistent. A skirt coating, also application-dependent, can further reduce friction and wear on the cylinder walls, leading to quieter operation and longer life.

This set is for an 8-cylinder engine and features a 4.145-inch bore with a dome volume of -12cc, designed to work with specific compression ratios. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a robust engine build that prioritizes performance and longevity, this JE Pistons set is a well-built option.
