Wiseco Chevy BB DRAG 1.120inchCH 4625A Piston Shelf Stock

If you're building a high-performance Chevrolet Big Block engine for drag racing, you need pistons that can handle the stress. These Professional Series pistons from Wiseco are built for those demanding applications. They start with a 2618 aluminum forging, which gives them improved tensile strength over standard aluminum alloys, making them well-suited for heavy to severe duty race builds.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features that improve ring seal. The crown is also fully machined for a clean finish. You'll also find an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and keep operation quieter. Plus, they feature forced pin oiling to ensure the wrist pin stays well-lubricated under extreme conditions.

Keep in mind these pistons are not CARB approved and cannot be shipped to California. They are sold individually, so be sure to order the correct quantity for your engine.
