Wiseco Chevy BB DRAG NITROUS 1.120CH Piston Shelf Stock Kit

If you're building a serious Chevrolet Big Block engine for drag racing, especially one that will see nitrous, this Wiseco Professional Series piston kit is a solid choice. These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength needed for the intense pressures of racing.

Wiseco packed a lot of smart features into these pistons. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, which is crucial for power and engine longevity. The piston crowns are fully machined, and they also come with forced pin oiling to keep things well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise, and makes them more resistant to seizing. These are built to handle heavy to severe duty race applications, so you can push your engine hard.

This kit includes a set of 8 pistons, each with a 4.600-inch bore and a 1.120-inch compression height. The pin diameter is 0.990 inches. Keep in mind these are not CARB approved and cannot be shipped to California. You'll want to refer to the manufacturer's instructions for any specific installation details or requirements.
