JE Pistons 4.040 SBC FT Set of 8 Pistons

If you're rebuilding a Small Block Chevy engine for serious performance, a strong set of pistons is where it all starts. This set from JE Pistons is built for those high-demand applications where durability and power are critical. They're forged in the USA using 2618 aluminum, a material known for its high tensile strength, making these pistons well-suited for engines that will be pushed hard.

JE Pistons has been in the game for over 75 years, and they've put that experience into these specific pistons. They feature a proprietary Forged Side Relief (FSR) design, which helps reduce friction and power loss by using a narrower skirt. This design also helps save weight, especially with the shorter wrist pin. Depending on the specific application, you might also find an accumulator groove to help manage combustion gas pressure, leading to better ring seal and consistent power. Some applications also include a skirt coating to further reduce friction and wear, which can also quiet down the engine operation.

This set includes eight flat-top pistons, each designed for a 4.040-inch bore. They are made 100% in the USA, ensuring you're getting a well-built component for your engine build. Keep in mind these are not CARB approved and cannot be shipped to California.
