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

Wiseco is well-known for making strong internal engine components, especially for high-performance applications. This Professional Series piston kit is built for serious racers and builders who push their engines hard. These pistons are designed to handle heavy to severe duty race builds, meaning they are made to withstand extreme conditions and high stress without failing.

Each piston is forged and machined in the USA from 2618 aluminum, which offers improved tensile strength for better durability under load. They feature precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, which is crucial for maintaining compression and preventing blow-by. The crown of each piston is also fully machined for a clean, consistent surface. For added performance and longevity, these pistons come with an ArmorGlide skirt coating. This coating helps reduce friction, making the engine run smoother and quieter, while also being resistant to seizure, which is a common issue in high-stress engines.

This kit includes forced pin oiling to ensure the wrist pins are properly lubricated, further enhancing durability. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance Big Block Chevrolet engine and need pistons that can handle the demands of racing, this Wiseco Professional Series kit is a solid option.
