Wiseco Chevy Big Block 4.605in Bore 1.155in CH 45.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco Professional Series pistons are built for the demands of serious racing and heavy-duty performance applications. The 4.605-inch bore size is specific to Chevrolet Big Block engines, and the 1.155-inch compression height, along with a 45.00 CC dish volume, is designed to work with specific crankshaft and connecting rod combinations to achieve your desired compression ratio.

Wiseco machines these pistons in the USA, incorporating features like precision ring grooves, anti-detonation grooves, and additional ring seal improvements to ensure reliable performance under extreme conditions. The crown is fully machined for accuracy, and the pistons feature forced pin oiling for better lubrication. A notable feature is the ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation, even in severe duty builds.

This set includes eight pistons, rings, and wrist pins, ready for installation in your high-performance Chevrolet Big Block engine. Please note that these pistons are not CARB approved and cannot be shipped to California.
