JE Pistons BBC .600 DOME Set of 8 Pistons

Forged from 2618 aluminum, these JE Pistons BBC pistons are built for serious performance builds. The 2618 alloy offers high tensile strength, which is crucial when you're pushing an engine hard, whether that's on the drag strip or in a high-performance street application. This set is specifically designed for BBC (Big Block Chevrolet) engines and comes with eight pistons, ready to be installed in your V8.

JE Pistons incorporates several design features to help your engine run better and last longer. The proprietary Forged Side Relief (FSR) forging design helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, which also saves weight. Depending on the specific application, these pistons may also include an accumulator groove. This groove helps manage combustion gas pressure, reducing ring flutter and improving the ring seal for more consistent power delivery. Some applications also feature a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet down engine noise.

Every aspect of these pistons, from the initial forging to the final machining, is done in the USA. This ensures a high level of quality control throughout the manufacturing process. The bore size is 4.530 inches, with a compression distance (CD) of 1.270 inches and a pin diameter of 0.990 inches. Please note that these pistons are not CARB approved and cannot be shipped to California. They are designed for specific engine and use applications to provide optimized performance and durability.
