Wiseco Chevy Big Block 4.280in Bore 1.395in CH 32.00 CC Piston Set

If you're building a serious performance Chevy Big Block engine, Wiseco's Professional Series forged pistons are a solid choice. These pistons are made in the USA from 2618 aluminum, which gives them improved tensile strength needed for the demands of racing and heavy-duty applications. They're designed to handle severe duty, meaning they can take a beating and keep performing when you push your engine hard.

Wiseco packs a lot of thoughtful features into these pistons. You'll find precision ring grooves, an anti-detonation groove, and other features to improve ring seal, which is crucial for both power and longevity. The fully machined crown ensures accuracy, and the forced pin oiling helps keep the wrist pin well-lubricated. Plus, they come with an ArmorGlide skirt coating that helps resist seizure, reduces friction, and makes for quieter operation. This set includes eight pistons, ready to be installed in your build.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are intended for racing and off-road use where emissions regulations may not apply. For a high-performance Big Block build, these Wiseco pistons offer a well-built foundation.
