JE Pistons BBC INV DOME Set of 8 Pistons

When you're building a high-performance big block Chevrolet engine and need pistons that can handle serious power, this set from JE Pistons is a solid choice. These aren't just off-the-shelf parts; they're forged and machined right here in the USA, using 2618 aluminum, which gives them the strong tensile strength needed for demanding applications. JE Pistons has been doing this for over 75 years, and they put that experience into every piston they make, tailoring them specifically for your engine and how you plan to use it, whether that's on the drag strip or a dirt track.

What sets these pistons apart is their proprietary Forged Side Relief (FSR) design. This means they've worked to minimize friction and reduce power loss by using a narrower skirt and a shorter wrist pin, which also helps shave off some weight. Depending on your specific application, you might also find features like an accumulator groove, which helps manage combustion gas pressure to keep your rings seated properly and maintain consistent power. Some applications also include a skirt coating that not only cuts down on friction and wear between the piston and cylinder wall but also helps quiet things down a bit during operation. The -28.0 cc inverted dome design is also a key factor in achieving your desired compression ratio for maximum performance.

This set includes eight pistons, all designed for a 4.500-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 optimal results, always refer to the manufacturer's installation instructions and ensure all supporting components are suitable for your high-performance build.
