Wiseco Chevy Big Block 4.560in Bore 1.520in CH 0.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for serious racers and builders who need robust components for heavy or severe duty race applications. The 4.560-inch bore size is specific to certain Chevy Big Block engine builds, and the 1.520-inch compression height, combined with a 0.00 CC piston dish, is designed to achieve a specific compression ratio when paired with the right cylinder heads and gasket combination.

Wiseco machines these pistons in the USA, incorporating features like precision ring grooves, anti-detonation grooves, and additional ring seal enhancements to ensure reliable performance under extreme stress. The crown is fully machined for accuracy, and the pistons include forced pin oiling to keep the wrist pins properly lubricated. A notable feature is the ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation, all crucial for longevity in high-performance engines.

This set includes eight pistons, along with premium rings, ready for installation in your Chevy Big Block. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and durability in a racing environment, these Wiseco Professional Series pistons are a solid option.
