Wiseco Chevy Big Block 4.615in Bore 1.155in CH 4.00 CC Piston Set

If you're building a serious performance Chevy Big Block engine, Wiseco's Professional Series forged pistons are a solid choice. These pistons are made from 2618 aluminum, which offers improved tensile strength for demanding applications. They're designed and machined right here in the USA, ensuring a high level of craftsmanship for your build.

Wiseco has packed these pistons with features to handle heavy to severe duty racing. You'll find precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling are also notable details that contribute to their robust design for high-performance engines.

This set includes eight pistons, each designed for a 4.615-inch bore with a 1.155-inch compression height. Remember, these are intended for competition builds and are not CARB approved, meaning they cannot be shipped to California. For serious engine work, these Wiseco pistons are a well-built option.
