JE Pistons LS ASYM FT 4.000STRK Set of 8 Pistons

When you're building a high-performance LS engine, you get a set of eight forged pistons with this JE Pistons kit. These are flat-top pistons designed for a 4.135-inch bore, and they include a 0.927-inch wrist pin. They're made from 2618 aluminum, which is known for its high tensile strength, making it a solid choice for engines that demand a lot of performance and durability.

JE Pistons has been around for over 75 years, and they build these pistons right here in the USA. They use a proprietary Forged Side Relief (FSR) design that helps reduce friction and save weight by using a shorter wrist pin and a narrower skirt. Depending on the specific application, these pistons might also come with an accumulator groove to help control combustion gas pressure, which can improve ring seal and keep power consistent. Some applications also include a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which can also help quiet down the engine operation.

Because these are specifically designed for the LS engine and your particular use, you can expect optimized performance and durability. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a serious engine build, these JE Pistons are a well-built option.
