Product Details

These JE Pistons BBC .515 Dome pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, making them well-suited for high-demand performance applications. Each piston in this set of eight is designed specifically for the BBC engine and its intended use, aiming for an optimized balance of performance and durability. They feature a .515 dome and are built for a 4.560 inch bore.

JE Pistons incorporates a proprietary Forged Side Relief (FSR) forging design, which helps to minimize friction and power loss by using a reduced skirt width. This design also contributes to weight savings, especially when paired with a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, reducing ring flutter and improving ring seal for more consistent power delivery. Some applications also feature a skirt coating designed to reduce friction and wear on the piston skirts and cylinder walls, which can also lead to quieter operation.

Every part of this piston set is manufactured 100% in the USA, reflecting JE Pistons' extensive experience in forged racing pistons. While these pistons are built for serious performance, please note they are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have the correct wrist pins and locks, as these are typically sold separately.
