Wiseco BBC Quick 8 +4cc Dome 1.155inch CH Piston Shelf Stock Kit

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in Chevrolet Big Block engines. The +4cc dome design is a specific choice for certain compression ratio targets, and the 1.155-inch compression height is critical for proper valve timing and piston-to-valve clearance in many BBC applications. This kit includes a set of eight pistons, designed to handle the demands of heavy to severe duty racing builds where reliability is just as important as power.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation features, and additional ring seal improvements. The crown is fully machined for a clean, consistent surface, and forced pin oiling helps keep the wrist pins lubricated under extreme conditions. They also feature an ArmorGlide skirt coating, which helps reduce friction for quieter operation and resists seizure, a common issue in high-stress engines.

This set is intended for builders who need robust components for high-performance engines. While these pistons are designed 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 assembly and break-in procedures to ensure optimal performance and longevity.
