Wiseco Chevy Big Block 4.320in Bore 1.270in CH 9.50 CC Piston Set

When you're building a serious Chevy Big Block for racing, you need components that can handle the stress. This set from Wiseco gives you eight forged pistons, ready to go into your engine. They're made from 2618 aluminum, which is known for its strength, and are forged and machined right here in the USA.

Wiseco packed these Professional Series pistons with features for demanding builds. You get precision ring grooves, an anti-detonation groove, and other features to help seal the rings better. The piston crowns are fully machined, and they even have forced pin oiling to keep things well-lubricated. Plus, they come with an ArmorGlide skirt coating that helps reduce friction and resist seizure, all while making operation quieter. These are built to handle heavy to severe duty race applications, so you can push your engine hard.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance builds where durability and strength are paramount.
