JE Pistons BBC .575 DOME Set of 8 Pistons

JE Pistons has been a leader in forged racing pistons for over 75 years, and they've put that experience into this set of BBC pistons. These aren't just generic pistons; they're engineered and forged right here in the USA using 2618 aluminum, which gives them the high tensile strength needed for serious performance builds. JE Pistons are known for being proven in competition, from dirt tracks to drag strips, so you know you're getting a well-built part that can handle the demands of a high-performance engine.

This set features a .575 dome design and is built for a 4.280-inch bore. JE's proprietary Forged Side Relief (FSR) forging design helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, which also saves weight. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, leading to better ring seal and consistent power. Some applications also get a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, which can also quiet down the engine operation.

This kit includes 8 pistons, each designed specifically for the BBC engine and its intended use, aiming for an optimized balance of performance and durability. Keep in mind these pistons are not CARB approved and cannot be shipped to California. They are designed for high-demand performance applications where strength and reliability are critical.
