Wiseco Chevy BB DRAG 1.245inchCH (6425A100) Piston Shelf Stock Kit

This kit includes a set of eight Wiseco Professional Series forged pistons, designed specifically for Chevrolet Big Block drag racing applications. Each piston features a 4.600-inch bore and a 1.245-inch compression height, with a 0.990-inch pin diameter. These pistons are engineered and forged in the USA from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for the demands of heavy to severe duty race builds.

The Professional Series pistons come equipped with ArmorGlide skirt coating, which helps reduce friction and noise while also resisting seizure. The fully machined crown includes precision ring grooves, an anti-detonation groove, and additional features designed to improve ring seal. Forced pin oiling is also incorporated to ensure proper lubrication under extreme conditions. These pistons are built to withstand the intense stress of drag racing, offering a solid option for serious racers and builders looking to push their engines to the limit.

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 fitment and assembly procedures.
