JE Pistons GM LS1 INV DM 6.098 Rod - Set of 8

JE Pistons has been a leader in forged racing pistons for over 75 years, and they've applied that experience to their extensive line of forged pistons for domestic engines. These pistons are engineered, forged, and machined entirely in the USA, specifically for each engine and racing application to offer the best balance of durability and performance. You'll find JE Pistons proving their worth in victory lanes across various racing disciplines.

This particular set is designed for GM LS1 engines and features a 3.905-inch bore. They are constructed from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for high-demand performance applications. The pistons incorporate JE Pistons' proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, saving additional weight. Depending on the specific application, these pistons may also include an accumulator groove to reduce pressure from combustion gases, leading to improved ring seal and consistent power. Some applications also feature a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, while also lowering operating noise.

This is a complete set of 8 pistons, ready for installation in your GM LS1 engine. Please note that these pistons are not CARB approved and cannot be shipped to California. They are designed for high-performance use and are a solid option for builders looking for proven forged piston technology.
