What specific engine configurations are these pistons designed for?

These pistons are designed for LS engines and are part of a set for 8-cylinder applications. They feature a 4.005 inch bore and a flat-top design. Always consult the manufacturer's detailed specifications to ensure compatibility with your specific engine build.

What materials are these pistons made from and why is that important?

These pistons are forged from 2618 aluminum. This material is chosen for its high tensile strength, which is crucial for handling the high demands and temperatures found in performance engine applications. Forging also creates a stronger, more durable piston compared to casting.

Are there any special coatings or designs on these pistons?

Yes, these pistons may include JE Pistons' proprietary Forged Side Relief (FSR) design, which helps reduce friction and weight. Depending on the application, they might also feature an accumulator groove for better ring seal and a skirt coating to reduce friction, wear, and noise.

Product Details

This is a set of 8 JE Pistons LS ASYM FT pistons, designed for high-performance LS engines. These pistons are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, making them well-suited for demanding applications where durability and performance are critical. They feature a flat-top design and are built to precise specifications for optimal engine function.

JE Pistons has over 75 years of experience in creating forged racing pistons. This particular set includes their proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by using a reduced skirt width. This design also contributes to saving weight by utilizing a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, reducing ring flutter and improving ring seal for consistent power delivery. Some applications also feature a skirt coating designed to reduce friction and wear on the piston skirts and cylinder walls, which can also help lower operating noise.

This piston set is engineered and machined 100% in the USA. It's important to note that these pistons are not CARB approved and cannot be shipped to California. They are designed for specific engine and use applications to provide optimized performance and durability, making them a solid choice for builders looking for proven performance.
