Wiseco Chevy Small Block 4.040in Bore 1.125in CH -1.70 CC Piston Set

This Wiseco piston set includes eight forged pistons, designed for Chevrolet small block engines with a 4.040-inch bore. These pistons feature a 1.125-inch compression height and a 0.927-inch pin diameter, and they come with premium rings to ensure a good seal. They are engineered and machined in the USA from 2618 aluminum, chosen for its improved tensile strength, making them well-suited for demanding builds.

Wiseco's Professional Series pistons are built to handle heavy to severe duty performance applications. They incorporate features like precision ring grooves, anti-detonation grooves, and additional ring seal improvements. The fully machined crown and forced pin oiling are also notable design elements. Additionally, these pistons include an ArmorGlide skirt coating, which helps resist seizure, reduces friction, and contributes to quieter operation. This set is intended for serious racers and builders who need durability and performance under extreme conditions.

Please note that this piston set is not CARB approved and cannot be shipped to California. It is designed for high-performance engine builds where durability and strength are paramount.
