JE Pistons LS ASYM DISH/INV DM 3.900 Set of 8 Pistons

If you're building a high-performance LS engine, getting the right pistons is crucial for durability and power. This set of eight Asymmetrical Dish/Inverted Dome pistons from JE Pistons is forged from 2618 aluminum, a material known for its high tensile strength, making it well-suited for demanding performance applications where reliability is key.

JE Pistons has been in the game for over 75 years, and they machine these pistons 100% in the USA, specifically for the LS engine and your intended use. They feature a proprietary Forged Side Relief (FSR) design that helps reduce friction and weight by using a shorter wrist pin and reduced skirt width. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, which can improve ring seal and prevent fluttering, leading to more consistent power delivery. Some applications also get a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet down engine noise.

This set is designed for a 4.065 inch bore and includes all eight pistons. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a serious LS build, these JE Pistons offer a well-built foundation for your engine's performance goals.
