JE Pistons 4.040 SBC FT Set of 8 Pistons

This is a set of eight JE Pistons, specifically designed for a 4.040 inch bore Small Block Chevy (SBC) engine. You get flat-top pistons, each made from 2618 aluminum, which is known for its high tensile strength, making it a solid choice for high-demand performance applications. These pistons are engineered and forged right here in the USA, drawing on JE Pistons' extensive experience in racing components.

JE Pistons uses a proprietary Forged Side Relief (FSR) forging design. This design helps minimize friction and power loss by using a reduced skirt width, and it also saves weight thanks to a shorter wrist pin. Depending on the specific application, these pistons may also feature an accumulator groove, which helps reduce pressure from combustion gases. This can lead to less ring fluttering and an improved ring seal, ensuring consistent power delivery. Some applications also include a skirt coating that works to reduce friction and wear on the piston skirts and cylinder walls, which can also help lower operating noise.

This set is designed specifically for the engine and its intended use, aiming for optimized performance and durability. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are made 100% in the USA.
