JE Pistons 400 SBC FLAT TOP Set of 8 Pistons

If you're building a high-performance 400 small-block Chevy, this set of eight flat-top pistons from JE Pistons is a solid choice. JE Pistons has been making forged pistons for decades, and these are built in the USA using 2618 aluminum. This material is chosen for its high tensile strength, which is exactly what you need when you're pushing an engine hard, whether that's on the drag strip or just for serious street performance.

These pistons feature JE Pistons' proprietary Forged Side Relief (FSR) design. This means they have a reduced skirt width, which helps minimize friction and power loss, and they use a shorter wrist pin to save even more weight. Depending on the specific application, you might also find an accumulator groove, which helps manage combustion gas pressure to keep the rings seated properly for consistent power. Some applications also include a skirt coating that further reduces friction and wear, helping to quiet down the engine and extend the life of the piston and cylinder wall.

This kit includes everything you need for an 8-cylinder engine, with a 4.165-inch bore and a -5.0cc dish for the flat-top design. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For serious engine builds, JE Pistons are a well-known name, and these are made 100% in the USA.
