JE Pistons LS ASYM DM 4000STRKR Set of 8 Pistons

If you're building a high-performance LS engine, you need pistons that can handle the stress. This set of 8 JE Pistons LS ASYM DM 4000STRKR pistons is forged from 2618 aluminum right here in the USA, giving you the strong tensile strength required for demanding applications. JE Pistons brings over 75 years of experience to the table, ensuring these pistons are built for both durability and performance.

These pistons feature JE's proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width. They also use a shorter wrist pin, further saving weight. Depending on the specific application, you might find an accumulator groove to help reduce combustion gas pressure, leading to better ring seal and consistent power, and a skirt coating that cuts down on friction and wear while also reducing operating noise. Each piston is designed specifically for the LS engine and its intended use, optimizing both performance and longevity.

This set is for an 8-cylinder engine with a 4.005-inch bore, a 1.115-inch compression distance, and a 0.927-inch pin. Please note that these pistons are not CARB approved and cannot be shipped to California. They are made 100% in the USA.
