JE Pistons LS Asymmetrical Domed Piston Set for 4.070-inch Bore – Part Number 312125

Description

Upgrade your high-performance engine with the JE Pistons LS Asymmetrical Domed Piston Set, designed specifically for 8-cylinder applications with a 4.070-inch bore diameter. Crafted from high-grade 2618 aluminum, these forged pistons are engineered for durability and maximum power output. Each piston features a proprietary Forged Side Relief (FSR) forging design that reduces friction and power loss by decreasing skirt width and saving weight with a shorter wrist pin. This design enhances engine efficiency and responsiveness, making it ideal for racing and demanding performance applications. The pistons also include an accumulator groove (application-dependent) that helps alleviate pressure from combustion gases, reducing ring flutter and promoting consistent power delivery. Additionally, the skirt coating minimizes friction and wear on piston skirts and cylinder walls, which extends engine life while simultaneously reducing operating noise. Precision-machined in the USA, these pistons are engineered for optimal performance and tailored to specific engine requirements, ensuring reliable operation in various racing environments. Please note, these pistons are not carburetor approved and require acknowledgment for carburetor compatibility. They are suitable for high-demand applications where durability and performance are critical, such as dirt track racing or drag racing, and are made to meet strict industry standards for quality and consistency.
