Wiseco Chevy Big Block 4.500in Bore 1.215in CH 40.00 CC Piston Set

If you're building a high-performance Chevrolet Big Block engine, these Wiseco Professional Series pistons are a solid option. They're designed for serious racers and builders who need parts that can handle heavy to severe duty performance applications. Wiseco crafts these pistons in the USA from 2618 aluminum, which gives them improved tensile strength for demanding builds.

You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal. Plus, they come with a special ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and makes for quieter operation. The fully machined crown also contributes to their overall well-built nature, ensuring they can stand up to the stress of racing.

This set includes eight pistons, each designed for a 4.500-inch bore with a 1.215-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. For serious engine builds, these Wiseco pistons offer a lot of custom-level performance and durability features.
