JE Pistons BBC .565 DOME Set of 8 Pistons

If you're building a high-performance Big Block Chevrolet engine, these JE Pistons BBC .565 Dome pistons are a solid choice. JE Pistons has been making forged pistons for decades, and this set is built for serious power. They're forged from 2618 aluminum, which gives them the high tensile strength needed for demanding applications where reliability is key.

What sets these pistons apart is their design, which is specific to the BBC engine and its intended use. They feature a proprietary Forged Side Relief (FSR) design that helps reduce friction and power loss by using a narrower skirt. This also saves weight, especially when paired with a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove, which helps manage combustion gas pressure to prevent ring flutter and maintain a consistent ring seal for steady power delivery. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, which can also lead to quieter operation.

Every part of this piston set is made in the USA, from the forging process to the final machining. This ensures a high level of quality control. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance builds and are a key component for anyone looking to maximize their BBC engine's potential.
