JE Pistons LS ASYM DM 4100STRKR Set of 8 Pistons

When you're building a high-performance LS engine, the pistons are a critical component that needs to handle serious stress. This set of eight JE Pistons LS ASYM DM 4100STRKR pistons is forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, making it well-suited for demanding performance applications where durability is key.

JE Pistons brings over 75 years of experience to these forged pistons, specifically designing them for the LS engine and its intended use. They feature a proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin for added weight savings. Depending on the specific application, these pistons may also include an accumulator groove to help control combustion gas pressure, reducing ring flutter and improving ring seal for consistent power delivery. Some applications also feature a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also contributing to quieter operation.

This set is designed for a 4.030-inch bore and includes all eight pistons, along with the necessary wrist pins. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a robust LS engine build that prioritizes both performance and longevity, these JE Pistons offer a solid foundation.
