Wiseco BBC inchQ16inch Heavy NOS +42cc 1.120inch CH Piston Shelf Stock Kit

Wiseco is well-known for making strong internal engine components, and their Professional Series forged racing pistons are a prime example of that commitment. If you're building a serious performance engine, especially one designed for heavy or severe duty race applications, these pistons are built to handle the stress. They are engineered, forged, and machined right here in the USA from 2618 aluminum, a material chosen for its improved tensile strength under extreme conditions.

These aren't just basic pistons; they come packed with features to improve performance and durability. You'll find precision ring grooves, an anti-detonation groove, and other features designed to enhance ring seal. The crown of each piston is fully machined, and they incorporate forced pin oiling to ensure the wrist pin stays well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which is a notable benefit in high-performance builds. This kit includes a set of eight pistons, ready for your Chevrolet Big Block build.

This piston set is designed to fit a wide range of Chevrolet Big Block vehicles, including models like the 1970-1975 Chevrolet Bel Air, 1970-1972 Chevrolet Biscayne, and 1973-1980 Chevrolet C10 Suburban, among many others. 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.
