JE Pistons BBC .700 DOME Set of 8 Pistons

If you're rebuilding a big block Chevrolet engine for serious performance, you're probably looking at forged pistons. These JE Pistons are built for those high-demand applications where durability and consistent power are critical. They're forged and machined right here in the USA using 2618 aluminum, which gives them the high tensile strength needed to handle the stress of racing and high-performance street use.

JE Pistons has been around for over 75 years, and they've put that experience into designs like their proprietary Forged Side Relief (FSR) forging. This design helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, which also shaves off some weight. Depending on the specific application, these pistons might also feature an accumulator groove to help manage combustion gas pressure, leading to better ring seal and more consistent power delivery. Some applications also include a skirt coating to further reduce friction and wear on the cylinder walls, which can also quiet down the engine's operation.

This set is designed specifically for an 8-cylinder big block Chevrolet engine, with a 4.350-inch bore and a .990-inch pin size. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a high-performance build, these pistons offer a solid foundation for your engine's top end.
