JE Pistons BBC NITROUS DOME GP Set of 8 Pistons

When you're building a high-performance big block Chevrolet engine, especially one intended for nitrous oxide, the pistons are a critical component. JE Pistons has been making forged racing pistons for over 75 years, and this set is designed specifically for those demanding applications. They're forged and machined right here in the USA, using 2618 aluminum, which gives them the high tensile strength needed to handle the intense pressures of a nitrous-fed engine.

This particular set features a dome design, which is common for nitrous applications to help achieve a desired compression ratio. They also incorporate JE's proprietary Forged Side Relief (FSR) forging design. This means they have reduced skirt width and a shorter wrist pin, which helps minimize friction and power loss while also saving weight. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, reducing ring flutter and improving ring seal for consistent power delivery. Some applications also benefit from a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet down engine noise.

This is a complete set of 8 pistons, ready to be installed in your engine build. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a serious engine build, especially one involving nitrous, these JE Pistons offer a well-built and proven solution.
