Wiseco Chevy Big Block 4.580in Bore 1.120in CH 15.60 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty engine builds. The 4.580-inch bore size is specific to certain Chevrolet Big Block applications, and the 1.120-inch compression height is a key measurement for achieving the correct deck height and piston-to-valve clearance in your engine build.

Wiseco machines these pistons in the USA, incorporating features like precision ring grooves, anti-detonation grooves, and additional ring seal improvements to ensure robust performance. The crown is fully machined for accuracy, and they include forced pin oiling to keep the wrist pins lubricated under extreme conditions. The ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, all crucial for longevity in severe duty applications.

This set includes eight pistons, designed to withstand the rigors of competition and high-performance street use. Please note that these pistons are not CARB approved and cannot be shipped to California. It's always recommended to consult the manufacturer's installation instructions for proper fitment and assembly procedures.
