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 coated?

Depending on the specific application, these pistons may come with a skirt coating. This coating is designed to reduce friction and wear on the piston skirts and cylinder walls, while also helping to reduce operating noise.

Can these pistons be shipped to California?

No, these pistons are not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

JE Pistons has been a leader in forged racing pistons for over 75 years, known for applying their experience to a wide range of domestic applications. This set of eight pistons is engineered and machined 100% in the USA, using 2618 aluminum for the high tensile strength needed in performance engines. They are designed specifically for your engine and intended use, aiming for the best combination of durability and performance.

These pistons feature JE Pistons' proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width. The design also saves weight with a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, which can prevent ring flutter and improve ring seal for consistent power. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet down operating noise.

This set is for a 4.610 inch bore with a 1.120 inch compression distance and a 0.990 inch pin. Please note that these pistons are not CARB approved and cannot be shipped to California.
