Wiseco Chevy Big Block 4.530in Bore 1.060in CH 45.00 CC Piston Set

Wiseco is well-known for making strong, reliable engine components, especially for high-performance applications. This Professional Series piston set is built for serious racers and builders who need top-tier performance and durability in their Chevy Big Block engines. These aren't your average pistons; they're designed from the ground up for heavy to severe duty race builds where every component has to perform under extreme stress.

Forged and machined right here in the USA from 2618 aluminum, these pistons offer improved tensile strength, which is crucial for handling the high pressures and temperatures found in a race engine. They feature precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, ensuring efficient combustion and preventing blow-by. The crown is fully machined for accuracy, and they come with forced pin oiling to keep the wrist pins lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and resist seizure, contributing to a quieter operation and longer life even under demanding conditions.

This set includes eight pistons, each designed for a 4.530-inch bore with a 1.060-inch compression height and a 0.990-inch pin diameter. If you're building a high-performance Chevy Big Block and need pistons that can handle the rigors of racing, this Wiseco set is a solid option. Please note that these are not CARB approved and cannot be shipped to California.
