About this part

Product Details

If you're building a high-performance 400 Small Block Chevy engine, a solid set of pistons is crucial for handling the power and stress. This set from JE Pistons is designed specifically for that kind of demanding application, offering a dome shape that works well with certain combustion chamber designs to optimize performance.

These pistons are forged from 2618 aluminum right here in the USA, a material known for its high tensile strength, which is exactly what you need when you're pushing an engine hard. JE Pistons also incorporates their proprietary Forged Side Relief (FSR) design. This means they've reduced the skirt width and used a shorter wrist pin, which helps cut down on friction and weight, ultimately leading to less power loss. Depending on the specific application, you might also find an accumulator groove to help manage combustion gas pressure, improving ring seal and keeping power consistent. Some applications also feature a skirt coating that further reduces friction and wear, making the engine run quieter and last longer.

This kit includes everything you need for an 8-cylinder engine, with a 4.125-inch bore size and a 0.927-inch pin diameter. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For serious engine builds, JE Pistons has a long track record of proven performance.
