What material are these JE 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.

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

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

Are these pistons compatible with all Big Block Chevrolet engines?

These pistons are designed specifically for BBC engines and come in a 4.310-inch bore size. It's important to verify that this bore size and the 0.990-inch wrist pin diameter match your specific engine build requirements.

Product Details

If you're building a high-performance Big Block Chevrolet (BBC) engine, these JE Pistons are a solid choice. This set includes eight pistons, each forged from 2618 aluminum, a material known for its high tensile strength, making it well-suited for demanding performance applications. They are designed specifically for BBC engines to offer an optimized combination of durability and performance, whether you're hitting the drag strip or the dirt track.

JE Pistons has applied over 75 years of experience to these components, and they are manufactured 100% in the USA. A notable feature is the proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width. This design also saves weight by using a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, improving ring seal and reducing ring flutter. Additionally, a skirt coating can be present to further reduce friction and wear on the piston skirts and cylinder walls, which also helps to quiet down engine noise.

This set is for a 4.310-inch bore with a 1.270-inch compression distance and a 0.990-inch wrist pin. Please note that these pistons are not CARB approved and cannot be shipped to California. They are designed for high-demand performance use and are a key component for rebuilding or upgrading your BBC engine.
