Wiseco Chevy Small Block 4.030in Bore 1.125in CH -19.00 CC Piston Set

If you're building a high-performance Chevrolet Small Block engine, this Wiseco Professional Series piston set is designed to handle some serious power. These pistons are made for demanding race applications where durability and consistent performance are critical. They feature a 4.030-inch bore size, a 1.125-inch compression height, and a -19.00cc dish volume, making them suitable for specific compression ratio targets in performance builds.

Wiseco forges these pistons from 2618 aluminum right here in the USA, which gives them improved tensile strength over cast aluminum. They're fully machined, including the crown, and come with precision ring grooves, anti-detonation grooves, and features to improve ring seal. You'll also find an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. The forced pin oiling design ensures the wrist pin stays well-lubricated under high stress.

This set includes eight pistons, designed to withstand heavy to severe duty performance use. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For serious engine builds, these Wiseco pistons offer a well-built foundation for significant power output.
