Wiseco Chevy BB DRAG NITROUS 1.270CH Piston Shelf Stock Kit

Forged from 2618 aluminum in the USA, these Wiseco Professional Series pistons are built for the demands of serious racing, especially in drag and nitrous applications. The 4.560 inch bore size and 1.270 inch compression height are specific dimensions that matter for engine builders looking to achieve precise compression ratios and valve timing in their Chevrolet Big Block builds.

Wiseco packs a lot of performance and durability features into these pistons. You'll find precision machined ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is critical for power and engine longevity under heavy load. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and operate more quietly, all important factors when you're pushing an engine hard. The fully machined crown ensures consistent combustion chamber volume from piston to piston.

This is a complete set of 8 pistons, designed for heavy to severe duty race applications. Forged pin oiling is also included to ensure proper lubrication to the wrist pin. Keep in mind these are not CARB approved and cannot be shipped to California.
