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

When you're building a high-performance LS engine, the pistons are a critical component. This set from JE Pistons includes eight asymmetric dish/inverted dome pistons, designed to handle the demands of serious performance applications. They are forged in the USA using 2618 aluminum, a material chosen for its high tensile strength, which is essential for engines pushed to their limits.

JE Pistons brings over 75 years of experience to these forged pistons. 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 reduce combustion gas pressure, preventing ring flutter and improving ring seal for consistent power delivery. Some applications also benefit from a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, leading to quieter operation.

This set is specifically designed for 8-cylinder LS engines with a 4.005-inch bore. Each piston has an inverted dome/dish shape with a volume of -16.60 cc, a 1.304-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 optimal performance and durability in your LS build, these JE Pistons offer a well-built solution.
