JE Pistons BBC BIG DUKE/CHIEF Set of 8 Pistons

Forged from 2618 aluminum, these JE Pistons BBC BIG DUKE/CHIEF pistons are built for high-demand performance applications. They are designed specifically for Big Block Chevrolet engines, offering an optimized combination of durability and performance that's been proven on the track. Each piston in this set of 8 features a dome top and measures 4.600 inches in bore diameter.

JE Pistons applies over 75 years of experience to their forged racing pistons, and this set is no exception. They incorporate 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, these pistons may also include an accumulator groove to reduce combustion gas pressure, improving ring seal and preventing ring flutter. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

Every component of this piston set is manufactured 100% in the USA, ensuring a high level of quality control. These pistons are intended for performance builds and are not CARB approved, meaning they cannot be shipped to California. If you're building a high-performance Big Block Chevrolet, this set of pistons is a solid option for achieving your power goals.
