JE Pistons 400 SBC DOME -12 Set of 8 Pistons

Forged from 2618 aluminum, these JE Pistons are built to handle the demands of a high-performance 400 SBC engine. This set includes eight pistons, each featuring a dome design and a 4.125-inch bore, ready to be installed in your build. JE Pistons brings over 75 years of experience to the table, focusing on creating durable and powerful components for racing applications.

The proprietary Forged Side Relief (FSR) forging design is a key feature here. It's engineered to reduce friction and power loss by using a narrower skirt width, and it also saves weight thanks to a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, which can improve ring seal and maintain consistent power. Some applications also feature a skirt coating designed to cut down on friction and wear, while also reducing noise. Every step, from forging to machining, is done right here in the USA, ensuring a well-built product for your engine.

This piston set is designed specifically for the 400 SBC engine and its intended use, aiming for optimized performance and durability. Please note that these pistons are not CARB approved and cannot be shipped to California. They are also subject to Prop 65 warnings.
