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

Starting with a 2618 aluminum forging, Wiseco builds these Professional Series pistons for serious racing applications. This specific piston is designed for Big Block Chevrolet engines with a 4.610 inch bore and features a 1.120 inch compression height. The 42cc dish is intended for specific compression ratio targets, often used with heavy nitrous oxide (NOS) applications, and includes an anti-detonation groove to help prevent detonation under extreme conditions.

You'll find precision ring grooves and additional features aimed at improving ring seal, which is crucial for power and engine longevity. The ArmorGlide skirt coating is applied to reduce friction and resist seizure, helping the piston move smoothly even under severe duty. These pistons are fully machined on the crown and feature forced pin oiling for better lubrication of the wrist pin.

These pistons are built to handle heavy to severe duty performance builds and are a solid option for racers and builders looking for a well-built component. They are designed and machined in the USA.
