JE Pistons LS ASYM DISH/INV DM 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 this set of pistons for LS engines. These aren't just off-the-shelf parts; they're engineered and forged right here in the USA using 2618 aluminum, a material known for its high tensile strength, making it ideal for high-demand performance applications. JE Pistons designs each set specifically for the intended engine and use, aiming for the best balance of durability and performance.

This set features a proprietary Forged Side Relief (FSR) forging design. This design helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, which also saves weight. Depending on the specific application, these pistons may also include an accumulator groove to help reduce pressure from combustion gases, which can prevent ring flutter and improve ring seal for more consistent power. Some applications also benefit from a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, while also making the engine run quieter.

This kit includes 8 pistons, each with a 4.135-inch bore and a 1.065-inch compression distance. The included wrist pin is 0.927 inches. Please note that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance use and are proven in various racing environments.
