Wiseco Chevy Big Block 4.600in Bore 1.155in CH 28.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty performance builds. The 4.600-inch bore size is specific to Chevrolet Big Block engines, and the 1.155-inch compression height is a key measurement for achieving the correct piston-to-deck clearance and compression ratio in your engine build.

Wiseco's Professional Series pistons come packed with features aimed at durability and performance. They include precision ring grooves, anti-detonation grooves, and additional features for improved ring seal. The crown is fully machined for accuracy, and they incorporate forced pin oiling to ensure the wrist pin stays well-lubricated under high stress. The ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which is a notable benefit in high-performance applications.

This set includes eight pistons, designed and machined in the USA. They are intended for severe duty performance applications where reliability and strength are paramount. Please note that these pistons are not CARB approved and cannot be shipped to California.
