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 crucial for high-demand performance applications.

What is the purpose of the Forged Side Relief (FSR) design?

The FSR forging design helps minimize friction and power loss by reducing the piston skirt width. It also contributes to weight savings by using a shorter wrist pin.

Are these pistons compatible with all BBC engines?

This set is specifically designed for BBC engines with a 4.500 inch bore. It is important to verify your engine's specifications to ensure proper fitment. Additionally, these pistons are not CARB approved and cannot be shipped to California.

Product Details

JE Pistons has been a leader in forged racing pistons for over 75 years, and they've put that experience into these BBC BLOWN ALKY DOME pistons. These are built for high-demand performance applications, forged and machined 100% in the USA using 2618 aluminum. This material gives them the high tensile strength you need when you're pushing your engine hard.

What sets these pistons apart is their specific design for each engine and use. They feature a proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width. This design also saves weight with a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove to help reduce pressure from combustion gases, 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 also helps cut down on operating noise.

This set includes 8 pistons, each with a 4.500-inch bore and a dome design. The kit comes with a 0.990-inch pin and has a compression height of 1.395 inches, with a volume of 30.1 cc for the dome. Please note that these pistons are not CARB approved and cannot be shipped to California.
