JE Pistons 632 BBC 12/14 DEG Set of 8 Pistons

When you're building a high-performance Big Block Chevrolet engine, you need pistons that can handle the stress and deliver consistent power. This set from JE Pistons includes eight forged pistons, specifically designed for 632 BBC applications with 12/14 degree cylinder head configurations. They are forged in the USA from 2618 aluminum, a material known for its high tensile strength, making these pistons well-suited for demanding performance builds.

JE Pistons brings over 75 years of experience to these components. They feature a proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, also saving weight. 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 more consistent power delivery. Some applications also benefit from a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, which can also lead to quieter operation.

This set is designed for a 4.610 inch bore with a flat top piston design. The wrist pin diameter is 0.990 inches, and the compression distance is 1.120 inches. It's important to note that these pistons are not CARB approved and cannot be shipped to California. JE Pistons are engineered and machined 100% in the USA, ensuring they are built for the ultimate combination of durability and performance, proven time and again in racing environments.
