Wiseco Chevy BB DRAG NITROUS 1.270CH Piston Shelf Stock Kit

Wiseco is well-known for making strong, reliable forged pistons for performance applications. This Professional Series piston kit is built for serious racers and builders who need parts that can handle extreme conditions. If you're putting together a heavy-duty drag racing engine for a Chevy Big Block, these pistons are designed to meet that challenge.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for demanding race builds. They feature precision ring grooves, an anti-detonation groove, and other features to help improve ring seal. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, makes operation quieter, and resists seizure. The fully machined crown is also a notable detail for performance builds.

This set includes eight pistons, each designed for a 4.530-inch bore with a 1.250-inch compression height and a 0.99-inch pin diameter. They are built to withstand heavy to severe duty performance applications, and the forced pin oiling helps keep things lubricated under stress. Keep in mind these are not CARB approved and cannot be shipped to California.
