Wiseco Chevy Big Block 4.625in Bore 1.060in CH 28.00 CC Piston Set

If you're building a high-performance Chevy Big Block engine for serious racing or severe duty, you need pistons that can handle the stress. This set of eight forged pistons from Wiseco is designed specifically for those demanding applications. They're made from 2618 aluminum, which offers improved tensile strength compared to other aluminum alloys, giving you a solid foundation for your build.

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 improve ring seal. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and makes for quieter operation, all crucial for longevity under heavy load. The fully machined crown ensures accuracy, and the forced pin oiling system keeps the wrist pins lubricated, which is vital for preventing wear in high-stress engines.

This set is built to withstand heavy to severe duty performance applications, meaning they're ready for the kind of abuse that breaks down lesser components. Keep in mind these are not CARB approved and cannot be shipped to California. For a robust engine build that can take a beating, this Wiseco piston set is a well-built choice.
