Wiseco Chevy BIG BLK DRAG 1.520CH 4280A Piston Shelf Stock

If you're building a serious drag racing engine for your Chevrolet Big Block, you need a piston that can handle the extreme demands. Wiseco's Professional Series forged pistons are built for just that. They start with 2618 aluminum, which is well-built for improved tensile strength, and are forged and machined right here in the USA.

These pistons come with a special ArmorGlide skirt coating. This isn't just for looks; it helps resist seizure, reduces friction, and makes for quieter operation, which is a notable benefit when you're pushing your engine hard. The fully machined crown also features precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. Plus, they have forced pin oiling to keep things well-lubricated under heavy load.

These are designed and built to withstand heavy to severe duty performance applications, so you can push your limits on the track. Keep in mind these are not CARB approved and cannot be shipped to California.
