Wiseco Chevy Big Block 4.560in Bore 1.120in CH 15.60 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in Chevy Big Block engines. The 4.560 inch bore size is specific for certain Big Block configurations, and the 1.120 inch compression height combined with a 15.60cc dish volume is designed to achieve a particular compression ratio when paired with your cylinder heads and block. This set includes eight pistons, ready for a heavy or severe duty rebuild.

Wiseco machines these pistons in the USA, incorporating features like precision ring grooves, anti-detonation grooves, and additional ring seal improvements to ensure a solid seal under high stress. The crown is fully machined for accuracy, and they feature forced pin oiling to keep the wrist pins lubricated. A notable feature is the ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly, all crucial for longevity in demanding applications.

This set is intended for builders who are pushing their engines hard, whether for racing or extreme performance street use. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
