Wiseco Chevrolet SB 23deg Turbo/Supercharger 4.125in Bore 4.00 in Dish Piston - set of 8

Wiseco is well-known for making strong, reliable internal engine components for performance applications. This set of eight Professional Series pistons is built for Chevrolet Small Block engines, specifically designed for turbocharger or supercharger setups. They feature a 4.125-inch bore and a 4.00-inch dish to accommodate specific compression ratios needed for boosted engines.

These pistons are forged and machined in the USA from 2618 aluminum, which offers improved tensile strength for demanding builds. They come with precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal, which is crucial for maintaining boost pressure and engine health. The ArmorGlide skirt coating helps reduce friction and resist seizure, while also contributing to quieter operation. The fully machined crown ensures accuracy and consistency across the set, and forced pin oiling helps keep the wrist pins lubricated under extreme conditions.

This piston set is designed and built to withstand heavy to severe duty performance applications, making them a solid choice for serious racers and builders who are pushing their engines to the limit. Because these are designed for high-performance, boosted applications, they are not CARB approved and cannot be shipped to California.
