Wiseco Chevy BB DRAG 1.120inchCH (6243A125) Piston Shelf Stock Kit

Wiseco is well-known for making strong, reliable internal engine components, especially for performance applications. This Professional Series piston kit is built for serious racers and builders who demand the best for their Chevrolet Big Block engine. These aren't just any pistons; they're designed from the ground up to handle the intense stress of heavy to severe duty racing builds, giving you the confidence to push your engine to its limits.

Each piston starts as a forging from 2618 aluminum, chosen for its improved tensile strength, which is crucial for high-performance engines. Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and other features that enhance ring seal. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and makes for quieter operation, all contributing to a more durable and efficient engine under extreme conditions. The fully machined crown also adds to the overall strength and precision of the piston.

This kit includes everything you need for an 8-cylinder engine, with a 4.625-inch bore and a 1.120-inch compression height. The forced pin oiling feature ensures the wrist pin stays well-lubricated, which is vital for longevity in high-stress applications. Please note that these pistons are not CARB approved and cannot be shipped to California.
