Wiseco Chevy BB DRAG NITROUS 1.270CH Piston Shelf Stock Kit

Forged from 2618 aluminum, these Wiseco pistons are built with improved tensile strength to handle the demands of serious racing. The 4.600-inch bore size is specific for Chevrolet Big Block engines, and the 1.270-inch compression height is a key measurement for setting up your engine's valve timing and piston-to-head clearance. This kit is designed for heavy to severe duty race applications, including drag racing and nitrous oxide use, where durability and performance are critical.

Wiseco has packed these Professional Series pistons with features to enhance performance and longevity. You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal. The crown is fully machined for accuracy, and they incorporate forced pin oiling to ensure the wrist pins stay well-lubricated under extreme conditions. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which are all important factors when pushing an engine to its limits.

This set includes eight pistons, ready for your next high-performance build. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
