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

This JE Pistons kit gives you a complete set of 8 asymmetrical dish/inverted dome pistons, ready for your LS engine build. These aren't your average 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. The asymmetrical design and inverted dome shape are specific to certain LS engine configurations, aiming to optimize combustion and airflow for improved performance and durability.

JE Pistons has packed a lot of experience into these components. You'll find their proprietary Forged Side Relief (FSR) forging design, which helps reduce friction and save weight by using a narrower skirt and a shorter wrist pin. Depending on the specific application within the LS family, these pistons might also include an accumulator groove to help manage combustion gas pressure, reducing ring flutter and ensuring a consistent seal for steady power. Some applications also feature a skirt coating that works to cut down on friction and wear, which can also lead to quieter operation.

When you're building an engine that needs to perform reliably under stress, starting with well-made pistons is key. These are made 100% in the USA, from the forging process to the final machining, ensuring a high level of control over the manufacturing. This set is designed for a 4.030 inch bore, with a 1.115 inch compression distance and a 0.927 inch wrist pin. Keep in mind that these are not CARB approved and cannot be shipped to California. For optimal results, always consult the manufacturer's installation guidelines for proper fitment and assembly procedures.
