Wiseco Chevy Big Block 4.630in Bore 1.270in CH 48.70 CC Piston Set

What you get in this Wiseco Professional Series piston set are eight forged pistons, ready to be installed in your Chevy Big Block engine. These aren't just any pistons; they're built from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial when you're pushing an engine hard. The set includes premium rings designed to work with the pistons for better sealing.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation features, and other ring seal improvements. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, makes operation quieter, and resists seizing, which is a big deal in high-performance applications. The fully machined crown and forced pin oiling are also notable features that contribute to their ability to handle heavy to severe duty race builds. These pistons are designed to remove limits for serious racers and builders.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a serious race engine, these are a solid option designed for the demands of competition.
