JE Pistons GM LS1 FT 6.200in Rod 3.898in Bore -2cc Dish - Set of 8

If you're building a high-performance GM LS1 engine, these forged pistons from JE Pistons are a solid choice. They're designed to handle the demands of serious performance applications, whether you're hitting the drag strip or building a powerful street machine. JE Pistons has been making top-tier forged pistons for over 75 years, and these are made entirely in the USA, using 2618 aluminum for the strength you need.

These pistons feature JE's proprietary Forged Side Relief (FSR) design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight too. Depending on the specific application, they might also include an accumulator groove to help manage combustion gas pressure, which improves ring seal and keeps power consistent. Some applications also get a skirt coating that further reduces friction and wear on the cylinder walls, while also cutting down on operating noise. The 3.898-inch bore size and -2cc dish flat top design are optimized for specific engine builds, ensuring you get the best combination of performance and durability.

This set includes eight pistons, along with the necessary wrist pins, and is designed for a 6.200-inch rod length. Keep in mind these are not CARB approved and cannot be shipped to California. For serious engine builds, these JE Pistons offer a well-built foundation for power and reliability.
