About this part

Product Details

When you're building a high-performance LS engine, especially for racing or demanding street use, the pistons are a critical component. This set of eight JE Pistons LS ASYM DM 4000STRKR pistons is designed to handle the stress and deliver consistent power. They are forged in the USA from 2618 aluminum, a material known for its high tensile strength, which is essential for engines pushed beyond stock limits.

JE Pistons brings over 75 years of experience to these components, engineering them specifically for the LS engine and performance applications. You'll find features like their proprietary Forged Side Relief (FSR) design, which helps minimize friction and reduce weight by using a narrower skirt and a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, leading to better ring seal and more consistent power delivery. Some applications also feature a skirt coating to further reduce friction and wear on the cylinder walls, which can also help quiet down engine noise.

This set is for an 8-cylinder engine with a 4.000-inch bore, a 1.115-inch compression distance, and a 0.927-inch wrist pin. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For serious LS engine builds, these JE Pistons offer a well-built foundation for significant power.
