Forged from 2618 aluminum alloy, these CP Pistons BRS Big Block Chevy pistons are built for high-performance street and race applications. The 4.625 inch bore size is specific to certain Big Block Chevy 588 cubic inch engine builds, and the 1.220 inch pin diameter ensures a strong connection for the connecting rod. Each piston features a +46.9cc dish volume, which is crucial for achieving the desired compression ratio with your specific cylinder heads and camshaft combination.

CP Pistons is known for their well-built components, and this set of eight pistons is no exception. The BRS (Big Rig Series) design is intended for demanding use, offering improved strength and durability over cast pistons. The material choice, 2618 aluminum, provides excellent thermal expansion properties, allowing the piston to maintain a precise fit within the cylinder bore even under extreme operating temperatures. This attention to material and design helps prevent piston slap and ensures efficient power transfer.

This set is made to order, meaning it's manufactured specifically for your purchase, so please allow for production time. It's important to note that these pistons are not CARB approved and cannot be shipped to California. When planning your engine build, ensure you have the correct connecting rods and piston rings to match the 1.220 inch pin size and the 4.625 inch bore for a proper installation.
