What is included in this piston set?

This set includes 8 JE Pistons LS ASYM FT pistons. Depending on the specific application, they may also include an accumulator groove and skirt coating. You will need to source wrist pins and rings separately.

What material are these pistons made from?

These pistons are forged from 2618 aluminum. This material is chosen for its high tensile strength, which is necessary for high-demand performance applications.

Are these pistons compatible with all LS engines?

These pistons are designed specifically for LS engines and performance applications, with a 4.125-inch bore. It's important to verify that this bore size and the piston design match your specific engine build and requirements.

Product Details

This is a set of 8 JE Pistons LS ASYM FT pistons, designed for high-performance LS engines. You get the pistons themselves, ready for installation. These pistons are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines that see demanding use. They feature a flat-top design and are built for a 4.125-inch bore.

JE Pistons has over 75 years of experience in making forged racing pistons, and these are no exception. They incorporate a proprietary Forged Side Relief (FSR) design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight in the process. Depending on the specific application, these pistons may also come with an accumulator groove to help manage combustion gas pressure, leading to better ring seal and consistent power. Some applications also include a skirt coating designed to cut down on friction and wear, which can also make the engine run a bit quieter.

Because these are performance pistons, they are engineered specifically for the LS engine and its typical use cases, aiming for a balance of durability and optimized performance. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For installation, you'll want to refer to JE Pistons' specific instructions to ensure everything is set up correctly for your build.
