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

Forged in the USA using 2618 aluminum, these JE Pistons are built for high-demand performance applications. This set is specifically designed for Big Block Chevrolet engines, featuring a flat top design with a 4.600-inch bore, 1.120-inch compression distance, and a 0.990-inch wrist pin. JE Pistons brings over 75 years of experience to the table, ensuring a combination of durability and performance proven on tracks from dirt to drag strips.

The proprietary Forged Side Relief (FSR) forging design is a key feature, minimizing friction and power loss by reducing skirt width. This design, along with a shorter wrist pin, also saves weight. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, which can improve ring seal and reduce ring flutter for more consistent power. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This set includes eight pistons, all made 100% in the USA. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For those building a high-performance Big Block Chevrolet, these JE Pistons offer an optimized combination of strength, weight savings, and reduced friction for demanding engine builds.
