JE Pistons BBC .515 DOME Set of 8 Pistons

If you're building a high-performance Big Block Chevrolet engine, a solid set of pistons is crucial for handling the stress and delivering power. 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 demanding performance applications where reliability is key.

JE Pistons brings over 75 years of experience to the table, and these pistons are forged and machined entirely in the USA. They feature a proprietary Forged Side Relief (FSR) design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, also saving weight. Depending on the specific application, these pistons may also include an accumulator groove to manage combustion gas pressure, improving ring seal and maintaining consistent power. Some applications also benefit from a skirt coating that further reduces friction and wear on the cylinder walls, leading to quieter operation and longer life.

This particular set is designed for a 4.530-inch bore with a 1.395-inch compression distance and a 0.990-inch wrist pin. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For serious engine builds, choosing pistons forged with advanced materials and proven designs, like these from JE Pistons, is a step towards achieving your performance goals.
