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

JE Pistons is known for making well-built forged racing pistons, with over 75 years of experience. They've put that knowledge into this set of pistons for LS engines. These aren't just generic parts; they're engineered and forged right here in the USA, specifically for high-demand performance applications. If you're building a serious LS engine, these pistons are built to handle the stress and deliver consistent power.

What sets these apart is the proprietary Forged Side Relief (FSR) design. This means they've got a reduced skirt width and a shorter wrist pin, which helps cut down on friction and power loss while also saving weight. Depending on your specific LS engine, you might also get an accumulator groove, which helps manage combustion gas pressure to prevent ring flutter and keep your rings sealing tight. Plus, some applications include a skirt coating that further reduces friction and wear, making your engine run quieter and last longer. They're made from 2618 aluminum, a strong material chosen for its high tensile strength, perfect for engines pushed to their limits.

This set includes eight pistons, each with a 4.130-inch bore. The kit comes with the pistons, wrist pins, and locks. Keep in mind these are not CARB approved and cannot be shipped to California. They are designed for performance builds and are a solid option for anyone looking to get the most out of their LS engine.
