Wiseco Chevy Small Block 4.030in Bore 1.062in CH -22.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in Chevy small block engines. The 4.030-inch bore size is a common upgrade for many small block Chevy builds, and the -22.00cc dish volume is designed to work with specific cylinder head chamber volumes to achieve your desired compression ratio. This set includes eight pistons, each meticulously machined in the USA to meet the demands of heavy to severe duty racing applications.

Wiseco has packed these pistons with features to ensure durability and performance under extreme conditions. The precision ring grooves are designed for optimal sealing, and additional features are included to improve ring seal, which is critical for power and engine longevity. The crown is fully machined for accuracy, and forced pin oiling helps keep the wrist pins lubricated. Additionally, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, making these pistons a well-built choice for high-stress builds.

When rebuilding or modifying your Chevy small block for racing, these Wiseco Professional Series pistons are a solid option. They are designed to handle the rigors of competition, offering improved tensile strength and features that contribute to overall engine reliability. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For optimal results, always refer to the manufacturer's installation instructions and recommended component pairings.
