Wiseco Chevy Big Block 4.605in Bore 1.060in CH 45.00 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components, especially for performance applications. This Professional Series piston set is built for Chevy Big Block engines and is designed for serious racers and builders who need parts that can handle heavy to severe duty use. These aren't just any pistons; they're forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength to stand up to the demands of high-performance builds.

You'll find a lot of thoughtful details in these pistons. They feature precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal. The crown is fully machined for accuracy, and they come with forced pin oiling to keep things well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and makes for quieter operation. These are the kinds of features that make a real difference when you're pushing an engine hard.

This set includes eight pistons, each designed for a 4.605-inch bore with a 1.060-inch compression height and a 0.990-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a serious race engine, these pistons are a solid option to consider for the core of your build.
