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

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in Big Block Chevrolet engines. The material choice offers improved tensile strength, crucial for handling the stresses of heavy to severe duty race builds, especially those incorporating nitrous oxide (NOS). The 42cc dish volume is a specific design choice that impacts compression ratio, and the 1.120-inch compression height is key for proper piston-to-valve clearance and deck height management in many BBC applications.

Wiseco has included several features to enhance performance and durability. The pistons have precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, which is vital for maintaining cylinder pressure and preventing blow-by under extreme conditions. They also come with a forced pin oiling feature to ensure the wrist pin receives adequate lubrication. The crown is fully machined for accuracy, and the skirt is treated with an ArmorGlide coating. This coating is designed to reduce friction, resist seizure, and contribute to quieter operation, all important factors when pushing an engine to its limits.

This kit is designed for builders who are serious about performance and need components that can withstand demanding use. These pistons are manufactured and machined in the USA. While these pistons are built for severe duty, it's important to note they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
