JE Pistons LS ASYM FT 6098OEM Set of 8 Pistons

Starting with a 2618 aluminum forging, these JE Pistons are built for serious performance in LS engines. This material offers the high tensile strength needed for demanding applications, ensuring durability when you push your engine hard. JE Pistons has been making forged racing pistons for over 75 years, and they engineer and machine these sets right here in the USA, specifically for each engine and racing application to give you the best combination of durability and performance.

You'll find a few notable design choices here that make a difference. The proprietary Forged Side Relief (FSR) forging design helps reduce friction and power loss by using a reduced skirt width, and it saves even more weight with a shorter wrist pin. Depending on the specific application, you might also get an accumulator groove, which helps reduce pressure from combustion gases. This can lead to less ring flutter and better ring seal for more consistent power. Some applications also include a skirt coating to cut down on friction and wear on the piston skirts and cylinder walls, which also helps reduce operating noise.

This set is designed for an 8-cylinder engine with a 4.030 inch bore and a flat top piston. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance LS engine, these pistons are a solid option backed by decades of racing experience.
