Wiseco Chevy Big Block 4.560in Bore 1.245in CH 42.00 CC Piston Set

This piston set from Wiseco includes eight forged pistons, designed for Chevrolet Big Block engines with a 4.560-inch bore. These are part of Wiseco's Professional Series, meaning they're built with no compromises for serious racing and heavy-duty applications. They feature a 1.245-inch compression height and a 42.00 CC valve relief volume.

Each piston is forged and machined in the USA from 2618 aluminum, chosen for its improved tensile strength under high stress. They come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown includes precision ring grooves, an anti-detonation groove, and features designed for better ring seal. To ensure longevity and performance, these pistons also have forced pin oiling.

Wiseco designed and built this set to handle the demands of severe duty performance builds. Please note that this part is not CARB approved and cannot be shipped to California. It is also subject to Prop 65 warnings.
