Wiseco Chevy Big Block 4.605in Bore 1.060in CH 48.70 CC Piston Set

Wiseco is well-known for making strong, reliable engine components, especially for high-performance applications. This Professional Series piston set is a prime example, built for serious racers and builders who demand the best for their Chevy Big Block engines. These aren't your average pistons; they're packed with custom-level features designed to handle the rigors of heavy to severe duty race builds, letting you push your engine's limits.

Each piston in this set is forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for durability under extreme conditions. You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal for better compression and performance. They also come with an ArmorGlide skirt coating that helps resist seizure, reduces friction, and contributes to quieter operation. The fully machined crown ensures accuracy and consistency across the set, and the forced pin oiling system helps keep the wrist pins properly lubricated.

This set includes eight pistons, each designed for a 4.605-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 stand up to severe duty, this Wiseco set is a solid option. Please note that these pistons are not CARB approved and cannot be shipped to California.
