Wiseco Chevy Big Block 4.605in Bore 1.155in CH 4.00 CC Piston Set

If you're rebuilding the heart of your Chevy Big Block for serious racing or heavy-duty performance, a strong set of pistons is where you start. This Wiseco Professional Series piston set is built from the ground up for those demanding applications. They're forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength to handle the intense pressures of high-performance engines.

Wiseco has packed these pistons with features that serious builders look for. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is critical for both power and longevity. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and keep operation quieter. The fully machined crown and forced pin oiling further add to their capability in severe duty builds.

This set includes eight pistons, each designed for a 4.605-inch bore with a 1.155-inch compression height and a 4.00 CC volume. Remember, these are intended for competition and heavy-duty use, and they are not CARB approved, meaning they cannot be shipped to California. If you're aiming for maximum performance and durability in your Big Block build, this Wiseco set is a solid choice.
