JE Pistons LS ASYM FT Set of 8 Pistons

JE Pistons has been a leader in forged racing pistons for over 75 years, and they've put that experience into these LS ASYM FT piston sets. If you're building a high-performance LS engine, these pistons are made to handle the demands of racing and serious street use. They're engineered and machined right here in the USA, designed specifically for your engine to give you the best combination of durability and performance.

These pistons use a proprietary Forged Side Relief (FSR) design. This means they have a reduced skirt width and a shorter wrist pin, which helps cut down on friction and power loss while also saving weight. Depending on the specific application, you might also find an accumulator groove, which helps manage combustion gas pressure to keep your rings sealed tight and maintain consistent power. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, and it can even help quiet down the engine's operation.

JE Pistons crafts these from 2618 aluminum, a material known for its high tensile strength, which is exactly what you need when you're pushing an engine hard. They are made 100% in the USA, ensuring you're getting a well-built part designed for optimized performance and longevity. This set includes 8 pistons, each with a flat top design, a 4.130-inch bore, a 1.304-inch compression distance, and a 0.927-inch pin. Please note that these are not CARB approved and cannot be shipped to California.
