Wiseco 4.630 Big Block Chevy Quick 16 Severe Duty +42cc Dome 1.120CH Piston Set

Wiseco is well-known for making strong, reliable internal engine components, especially for high-performance applications. This Professional Series piston set is built for Big Block Chevy engines that demand serious durability. These aren't your average pistons; they're forged from 2618 aluminum, which gives them improved tensile strength over other materials, making them well-suited for heavy to severe duty performance builds where reliability is key.

Each piston in this set features precision machined ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The crown is also fully machined, and they come with forced pin oiling to ensure the wrist pins stay well-lubricated under extreme conditions. Plus, they have an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. This set is designed for a 4.630 inch bore with a 1.120 inch compression height and a +42cc dome volume.

This set includes eight pistons, premium rings, and is designed and built in the USA. Please note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance Big Block Chevy for demanding use, these pistons are a solid option to consider.
