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 crucial for handling the demands of racing or serious street use. This set of eight dome-top pistons from JE Pistons is forged from 2618 aluminum, a material known for its high tensile strength, making it well-suited for engines that push the limits.

JE Pistons has been in the game for over 75 years, and they machine these pistons 100% in the USA. They've incorporated their proprietary Forged Side Relief (FSR) design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight in the process. Depending on the specific application, these pistons may also feature an accumulator groove to manage combustion gas pressure, which helps prevent ring flutter and ensures a consistent ring seal for reliable power. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet down engine noise.

This particular set is designed for a 4.165-inch bore with a 1.100-inch compression distance and includes a 0.927-inch pin. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a robust engine build that needs pistons built for durability and performance, this JE Pistons set is a well-built option.
