Product Details
If you're rebuilding a Small Block Chevrolet 400 engine, especially one with an 18-degree cylinder head setup, these JE Pistons flat-top pistons are a solid choice. JE Pistons has been making performance pistons for a long time, and these are forged right here in the USA from 2618 aluminum. This material gives them the strong tensile strength needed for engines that are pushed hard, whether that's on the track or just in spirited driving.
What sets these apart is how they're made specifically for the application. They use a proprietary Forged Side Relief (FSR) design, which helps reduce friction and power loss by using a narrower skirt. Some applications also get a skirt coating to further cut down on friction and wear, making the engine run a bit quieter and smoother. There's also an accumulator groove that can help reduce combustion gas pressure, which keeps the piston rings seated better for consistent power delivery. This piston is for the right side application.
Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance applications and are a well-built component for your engine build.
