JE Pistons LS ASYM DM 6098 OEM Set of 8 Pistons

If you're rebuilding the heart of your LS engine for serious performance, a set of high-quality pistons is where you start. This JE Pistons LS ASYM DM 6098 set is built for demanding applications, offering a solid foundation for boosted or naturally aspirated builds that need to hold up under pressure. These aren't just any pistons; they're forged from 2618 aluminum right here in the USA, a material chosen for its high tensile strength, which is crucial when you're pushing an engine hard.

JE Pistons brings over 75 years of experience to the table, and it shows in the details. You'll find their proprietary Forged Side Relief (FSR) design, which helps minimize friction and save weight by using a reduced skirt width and a shorter wrist pin. Depending on your specific LS application, these pistons may also feature an accumulator groove to help control combustion gas pressure, leading to better ring seal and 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 quiet down engine noise.

This set includes eight pistons, each with a 4.070-inch bore, a 1.340-inch compression distance, and a 0.945-inch pin. They are designed specifically for LS engines to optimize performance and durability. Please note that this part is not CARB approved and cannot be shipped to California.
