Wiseco Chevy Big Block 4.615in Bore 1.120in CH 42.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for high-performance applications. This Professional Series piston set is a prime example, built for Chevy Big Block engines with a 4.615-inch bore. These aren't your average pistons; they're designed for serious racers and builders who push their engines hard, handling heavy to severe duty performance builds.

Crafted from 2618 aluminum right here in the USA, these pistons are forged and machined for improved tensile strength. You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal, which is crucial for keeping combustion pressure where it belongs. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling further contribute to their durability and performance under demanding conditions.

This set includes eight pistons, each with a 1.120-inch compression height and a 0.990-inch pin diameter. Keep in mind these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance Chevy Big Block and need components that can handle extreme stress, this Wiseco set is a solid option.
