Wiseco Chevy BB DRAG 1.120inchCH (6243AS) Piston Shelf Stock Kit

Forged from 2618 aluminum right here in the USA, these Wiseco pistons are built for serious performance in your Chevrolet Big Block engine. The 4.500 inch bore size and 1.120 inch compression height are key dimensions that determine how these pistons will work with your specific cylinder heads and crankshaft, making them a critical component for rebuilding or upgrading your engine for heavy to severe duty race applications.

Wiseco has packed these Professional Series pistons with features to handle the demands of racing. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal and durability under extreme conditions. The fully machined crown ensures consistent combustion chamber volume, while the forced pin oiling system helps keep the wrist pin lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise, and resists seizure, all contributing to a more robust and reliable engine build.

This kit includes a set of 8 pistons, ready for installation in your Big Block Chevy. 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.
