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. What you get in this JE Pistons kit is a complete set of eight asymmetric dish/inverted dome pistons, ready to be installed in your engine. These aren't just off-the-shelf parts; they're forged in the USA using 2618 aluminum, a material chosen for its high tensile strength, which is exactly what you need when you're pushing an engine hard.

JE Pistons brings over 75 years of experience to these components, and it shows. They feature a proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, saving weight in the process. Depending on your specific application, you might also find an accumulator groove, designed to reduce combustion gas pressure and improve ring seal for consistent power delivery. Some applications also include a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which can also help quiet down the engine's operation.

These pistons are made 100% in the USA and are designed specifically for each engine and use application, aiming for optimized performance and durability. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For any performance build, especially one involving an LS engine, using well-built forged pistons like these is a solid choice for reliability and power.
