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

This is a set of eight JE Pistons, specifically designed for LS engines. You get the pistons themselves, ready to be installed in your build. These aren't just any pistons; they're forged from 2618 aluminum right here in the USA, a material known for its high tensile strength, making it ideal for high-demand performance applications where durability is key. JE Pistons has been in the forged racing piston game for over 75 years, and they engineer these pistons for specific engines and racing uses to get you the best combination of lasting power and reliability.

What sets these apart is their design. They feature JE's proprietary Forged Side Relief (FSR) forging, which helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, saving weight too. Depending on the specific application, you might also find an accumulator groove, which helps manage combustion gas pressure to improve ring seal and keep power consistent. 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 engine noise. These are made 100% in the USA, ensuring you're getting a well-built part for your engine.

This particular set is for an 8-cylinder engine with a 4.155-inch bore. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
