JE Pistons LS ASYM DISH/INV DM Set of 8 Pistons

When you're building a high-performance LS engine, the pistons are a critical component that needs to handle serious stress. This set of eight asymmetrical dish/inverted dome pistons from JE Pistons is designed specifically for LS engines, offering a robust solution for demanding builds. They are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, making these pistons well-suited for applications where durability and performance are paramount.

JE Pistons brings over 75 years of experience to their forged piston designs. These pistons feature a proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin, also saving weight. Depending on the specific application, they may also include an accumulator groove to help control combustion gas pressure, reducing ring flutter and improving ring seal for consistent power delivery. A skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation and longer life.

This set is engineered for a 4.155-inch bore and includes all eight pistons, ready for your engine build. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For optimal performance and longevity in your LS engine, choosing pistons built to withstand high-demand applications is key, and JE Pistons has a proven track record in racing environments.
