Wiseco Chevy Small Block 4.030in Bore 1.250in CH 13.50 CC Piston Set

This Wiseco Professional Series piston set includes eight pistons, designed for Chevrolet small block engines with a 4.030-inch bore. These pistons are built for serious racers and builders who need components that can handle heavy to severe duty performance applications. They are forged and machined in the USA from 2618 aluminum, chosen for its improved tensile strength, which is crucial for high-stress engine builds.

Each piston features precision ring grooves, an anti-detonation groove, and other features to improve ring seal, helping to ensure consistent compression and performance under demanding conditions. The crown is fully machined for accuracy, and they come with forced pin oiling to keep the wrist pins lubricated. Additionally, these pistons have an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation.

This set is intended for builders who are looking to push the limits of their engine's performance. 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 specific guidelines and recommended assembly procedures.
