Wiseco Chevy Small Block 4.020in Bore 1.250in CH -5.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston set is a prime example, built for Chevy Small Block engines and designed for serious racers and builders who push their engines hard. If you're rebuilding a performance engine that needs to handle heavy or severe duty, these pistons are made to take that kind of stress.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for demanding builds. They come with precision ring grooves, anti-detonation grooves, and other features to help seal the rings better. You'll also find an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and makes for quieter operation. The fully machined crown and forced pin oiling are details that show these are built for serious performance where every component matters.

This set includes eight pistons, each designed for a 4.020-inch bore with a 1.250-inch compression height and a -5.00cc dish. Remember, these are not CARB approved and cannot be shipped to California. For a high-performance rebuild that needs robust internal components, this Wiseco set is a solid choice.
