Wiseco Chevy Big Block 4.605in Bore 1.120in CH 42.00 CC Piston Set

If you're building a high-performance Chevrolet Big Block engine for serious racing or heavy-duty use, a strong set of pistons is crucial. This Wiseco Professional Series piston set is designed to handle the extreme demands of severe duty applications. They are forged and machined right here in the USA from 2618 aluminum, a material known for its improved tensile strength, making these pistons well-built for the stress of racing.

Wiseco has packed these pistons with features to ensure reliability and performance. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The piston crowns are fully machined for a clean combustion chamber, and they come with forced pin oiling to keep the wrist pins lubricated under high loads. Plus, the ArmorGlide skirt coating helps reduce friction and resist seizure, contributing to quieter operation and longer life.

This set includes eight pistons, each with a 4.605-inch bore, a 1.120-inch compression height, and a 42cc combustion chamber volume. They are designed to be a solid option for builders who need components that can withstand the rigors of competition. Please note that these pistons are not CARB approved and cannot be shipped to California.
