What material are these JE Pistons made from?

These pistons are forged from 2618 aluminum. This alloy 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 allows for a shorter wrist pin, which further saves weight.

Are these pistons compatible with all Big Block Chevrolet engines?

While designed for BBC engines, specific dimensions like bore size and compression distance are critical. Always verify these specifications against your engine build requirements and consult manufacturer fitment data for confirmation.

Product Details

If you're building a high-performance Big Block Chevrolet engine, getting the right pistons is crucial for durability and power. This set of eight JE Pistons is forged from 2618 aluminum, a material known for its high tensile strength, making it well-suited for the demands of racing and performance applications. These pistons are designed specifically for BBC engines, ensuring they work correctly with your specific setup.

JE Pistons uses a proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width. This design also allows for a shorter wrist pin, saving additional weight. Depending on the specific application, these pistons may also feature an accumulator groove to reduce combustion gas pressure, which helps prevent ring flutter and improves ring seal for consistent power delivery. Some applications also include a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise.

Every part of this piston set is made in the USA, from the forging process to the final machining. This ensures a high level of quality control. The bore size is 4.280 inches, with a compression distance of 1.645 inches and a pin diameter of 0.990 inches. Please note that these pistons are not CARB approved and cannot be shipped to California.
