Product Details

When you're building a high-performance Big Block Chevrolet engine, the pistons are a critical component. This set of eight dome pistons from JE Pistons is forged from 2618 aluminum, a material known for its high tensile strength, making it well-suited for the demanding conditions of racing and high-output street applications. JE Pistons has been making forged pistons for over 75 years, and they engineer and machine these right here in the USA.

These pistons feature JE's proprietary Forged Side Relief (FSR) design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight in the process. Depending on the specific application, they may also include an accumulator groove to help manage combustion gas pressure, which can prevent ring flutter and improve ring seal for more consistent power delivery. Some applications also receive a skirt coating to further reduce friction and wear on the cylinder walls, leading to quieter operation and longer life. Each piston is designed specifically for the BBC engine and its intended use, aiming for optimized performance and durability.

This set includes all eight pistons, ready for your build. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have the correct rings and connecting rods to match the piston specifications, including the 0.990-inch wrist pin diameter and the 4.280-inch bore size.
