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 chosen for its high tensile strength, which is crucial for engines pushed hard in racing or high-performance street applications. JE Pistons has been doing this for over 75 years, and they put that experience into making sure these pistons are built to last and perform when you need them most.

What sets these apart is JE's proprietary Forged Side Relief (FSR) design. This means the pistons have a reduced skirt width and a shorter wrist pin, which helps minimize friction and power loss while also saving weight. Depending on your specific application, you might also find an accumulator groove, which helps manage combustion gas pressure for a better ring seal and more consistent power delivery. Some applications also include a skirt coating that further reduces friction and wear on the cylinder walls, leading to quieter operation and longer life for both the piston and the cylinder. Each piston is precisely machined for a 4.030-inch bore and includes a 0.927-inch pin.

Because these pistons are engineered specifically for the LS engine and the intended use, they offer an optimized balance of performance and durability. They are made 100% in the USA, ensuring a high standard of manufacturing. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a serious performance LS engine, these pistons are a solid choice backed by decades of racing success.
