Wiseco Chevy Big Block 4.605in Bore 1.120in CH 15.60 CC Piston Set

If you're building a serious performance Chevrolet Big Block engine, Wiseco's Professional Series forged pistons are a solid choice. These pistons are designed for heavy to severe duty race applications, meaning they're built to handle the extreme stresses of high-performance driving. They start with 2618 aluminum, a well-known material for its improved tensile strength, which is crucial for pistons that endure high combustion pressures and temperatures.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features that improve ring seal. This attention to detail helps ensure efficient combustion and reduces the risk of blow-by. The fully machined crown also contributes to consistent performance. For added durability and reduced friction, these pistons come with an ArmorGlide skirt coating, which helps prevent seizure, lowers friction, and makes for quieter operation. They also feature forced pin oiling to keep the wrist pin lubricated under demanding conditions.

This set includes eight pistons, each designed for a 4.605-inch bore with a 1.120-inch compression height and a 0.990-inch pin diameter. Keep in mind these are intended for racing and performance builds and are not CARB approved, so they cannot be shipped to California. If you're aiming for maximum performance and durability in your Big Block build, these Wiseco pistons are a well-made option.
