Wiseco Chevy BB 396/427/454/502 Dome 25cc x 1.270 CH Piston Kit

This kit includes a set of eight forged aluminum pistons from Wiseco, designed for Chevrolet Big Block engines. These pistons feature a 25cc dome volume and a 1.270 inch compression height, with a bore size of 4.280 inches. They are built for serious racers and builders who need components that can handle heavy to severe duty performance applications.

Crafted from 2618 aluminum in the USA, these pistons are forged and machined for improved tensile strength. You'll find precision ring grooves, anti-detonation grooves, and other features designed to enhance ring seal. The pistons also come with an ArmorGlide skirt coating, which helps resist seizure, reduces friction, and contributes to quieter operation. The fully machined crown and forced pin oiling are additional details that show these are made for demanding builds.

Because these are intended for high-performance racing, they are not CARB approved and cannot be shipped to California. If you're rebuilding a high-performance or racing engine, these Wiseco pistons are a solid option for building a strong foundation.
