Wiseco Chevy Big Block 4.310in Bore 1.645in CH 32.00 CC Piston Set

If you're building a serious performance Chevrolet Big Block engine, these Wiseco Professional Series forged pistons are a solid choice. They're made in the USA from 2618 aluminum, which is a strong material chosen for its high tensile strength, making these pistons well-suited for heavy to severe duty race applications. The machining on these pistons is precise, featuring anti-detonation grooves and other features designed to improve ring seal, which is critical for maintaining compression and power under extreme conditions.

Wiseco also includes an ArmorGlide skirt coating on these pistons. This coating helps reduce friction between the piston skirt and cylinder wall, which can lead to quieter operation and improved durability by resisting seizure. The fully machined crown ensures accuracy, and the forced pin oiling system helps keep the wrist pin properly lubricated, a vital detail for longevity in high-performance builds. This set includes eight pistons, ready for your next engine project.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a build where every component needs to perform under pressure, these Wiseco pistons are a well-built option.
