Wiseco Chevy BB DRAG NITROUS 1.270CH Piston Shelf Stock Kit

If you're building a serious drag racing engine for a Chevy Big Block, this piston kit from Wiseco is a solid choice. These are their Professional Series forged pistons, meaning they're built with no compromises for heavy-duty race applications. They're designed to handle the extreme demands of nitrous oxide injection and severe duty use, giving you the confidence to push your engine to its limits.

Wiseco crafts these pistons right here in the USA from 2618 aluminum, which offers improved tensile strength for better durability under high stress. You'll find precision machined ring grooves, anti-detonation features, and extra ring seal enhancements to ensure a tight seal and efficient combustion. The piston crowns are also fully machined, and they feature forced pin oiling to keep the wrist pins properly lubricated. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly.

This kit includes a set of eight pistons, each designed for a 4.500 inch bore with a 1.270 inch compression height and a 0.99 inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a serious race build, this Wiseco kit offers a well-built foundation.
