Wiseco Chevy Big Block 4.500in Bore 1.060in CH 48.70 CC Piston Set

When you're building a serious performance engine for your Chevy Big Block, you want parts that can handle the stress. This set includes eight forged pistons from Wiseco, designed for heavy to severe duty racing applications. They're made from 2618 aluminum, which gives them improved tensile strength compared to other aluminum alloys, making them well-suited for the demands of high-performance 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 fully machined crown ensures a clean combustion chamber, and they come with forced pin oiling to keep the wrist pins lubricated under extreme conditions. Plus, they feature an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. These are built for racers and builders who need reliable performance when pushing their engines to the limit.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete engine build, you'll want to ensure you have all the necessary supporting components like rings, connecting rods, and bearings that are compatible with these specifications.
