JE Pistons 400 SBC .165 DOME Set of 8 Pistons

When you're building a high-performance 400 SBC engine, the pistons are a critical component that needs to handle serious stress. This set from JE Pistons includes eight forged pistons, specifically designed for the 400 Small Block Chevrolet engine. They feature a .165 dome to help achieve your desired compression ratio, and the 4.130-inch bore size is standard for many 400 SBC builds.

JE Pistons uses a proprietary Forged Side Relief (FSR) forging design, which means these pistons have reduced skirt width to minimize friction and power loss. They're made from 2618 aluminum, a well-built material that offers the high tensile strength needed for demanding performance applications. Depending on the specific application, these pistons may also come with a skirt coating to reduce friction and wear, and an accumulator groove to help manage combustion gas pressure for a better ring seal. Every part of this set is forged and machined right here in the USA, ensuring you're getting a product with a long history of proven performance on the track.

This kit includes the eight pistons, wrist pins, and locks needed for installation. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
