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 from JE Pistons, part number 312114, is designed specifically for LS applications and is forged in the USA from 2618 aluminum. This material is chosen for its high tensile strength, which is crucial for engines that see demanding use, whether on the track or the street. JE Pistons brings over 75 years of experience to the table, focusing on creating pistons that balance durability with performance.

This particular set features a dome design and a 4.130-inch bore size, with a 1.115-inch compression distance and a 0.927-inch pin diameter. JE Pistons incorporates a proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin, saving weight in the process. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, improving ring seal and maintaining consistent power. Some applications also feature a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, which can also help lower operating noise.

This set includes eight pistons, all manufactured and machined 100% in the USA. It's important to note that this part is not CARB approved and cannot be shipped to California. If you're looking for pistons built for serious performance and durability in your LS engine, this JE Pistons set is a well-built option.
