Wiseco Chevy Big Block 4.530in Bore 1.155in CH 45.00 CC Piston Set

If you're building a serious performance engine for your Chevy Big Block, 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 for demanding applications. They're designed to handle heavy to severe duty racing builds, so you can push your engine hard without worrying about reliability.

Wiseco packs a lot of features into these pistons. You get precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The crown is fully machined, and they include forced pin oiling to keep things well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and resist seizure, leading to quieter operation and better durability. These are built for racers who need top-notch performance and durability.

This set includes eight pistons, each with a 4.530-inch bore, a 1.155-inch compression height, and a 45.00 cc combustion chamber volume. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a high-performance build, these Wiseco pistons are a well-built option.
