JE Pistons BBC .475 DOME Set of 8 Pistons

If you're building a high-performance Big Block Chevrolet engine, these JE Pistons are a solid choice. This set includes eight pistons, each featuring a .475-inch dome designed for a 4.560-inch bore. JE Pistons has been a leader in forged racing pistons for over 75 years, and they engineer and machine these right here in the USA.

These pistons are forged from 2618 aluminum, which gives them the high tensile strength needed for demanding performance applications. They incorporate JE's proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width. Some applications also include an accumulator groove to help manage combustion gas pressure, leading to better ring seal and consistent power. Depending on the specific application, a skirt coating may also be applied to further reduce friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise.

This kit is designed specifically for the engine and intended use, aiming for optimized performance and durability. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
