Wiseco Chevy Small Block 4.020in Bore 1.550in CH -15.00 CC Piston Set

This is a set of eight Wiseco Professional Series forged pistons, designed for Chevrolet Small Block engines. You get pistons with a 4.020-inch bore, a 1.550-inch compression height, and a -15.00cc dish volume. They also feature a 0.927-inch pin diameter. These pistons are built for serious racers and builders who need components that can handle heavy to severe duty performance applications.

Each piston is forged and machined in the USA from 2618 aluminum, which offers improved tensile strength for demanding builds. They come with an ArmorGlide skirt coating that helps resist seizure, reduces friction, and contributes to quieter operation. The fully machined crown includes precision ring grooves, an anti-detonation groove, and additional features designed to improve ring seal. For added durability and lubrication, these pistons are equipped with forced pin oiling.

These pistons are intended for high-performance engine builds where reliability under extreme stress is critical. Please note that this piston set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
