Wiseco Chevy Big Block 4.500in Bore 1.270in CH 15.00 CC Piston Set

If you're rebuilding a high-performance Chevrolet Big Block engine for serious racing or heavy-duty applications, a strong set of pistons is crucial. This Wiseco Professional Series piston set is designed to handle the intense demands of severe duty builds, offering a solid foundation for your engine's power and longevity.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is essential for withstanding the high pressures and temperatures found in racing engines. Wiseco has incorporated several features to enhance performance and durability, including precision ring grooves, anti-detonation grooves, and additional ring seal improvements. The fully machined crown ensures consistent combustion chamber volume, while forced pin oiling helps keep the wrist pins properly lubricated under extreme conditions. Additionally, the ArmorGlide skirt coating reduces friction and resistance to seizure, contributing to quieter operation and extended piston life.

This set includes eight pistons, each with a 4.500-inch bore, a 1.270-inch compression height, and a 0.990-inch pin diameter. They are designed to work with 15.00 CC combustion chambers. Please note that these pistons are not CARB approved and cannot be shipped to California. For optimal installation and performance, always refer to the manufacturer's detailed specifications and recommended build procedures.
