Wiseco Chevy Big Block 4.625in Bore 1.120in CH 38.00 CC Piston Set

What you get in this box is a set of eight Wiseco Professional Series forged pistons, ready to go into your Chevy Big Block engine. These aren't your average pistons; they're built from 2618 aluminum right here in the USA, chosen for its strong tensile strength, which is crucial when you're pushing an engine hard. They're designed for serious racers and builders who need components that can handle the demands of heavy to severe duty racing applications.

Wiseco has packed these pistons with features to help them perform and last. You'll find precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal, which means better compression and less blow-by. The pistons also come with an ArmorGlide skirt coating. This coating is there to reduce friction, help prevent seizure if things get hot, and contribute to quieter operation. The fully machined crown ensures accuracy, and the forced pin oiling system helps keep the wrist pins well-lubricated under high stress.

If you're building a high-performance Big Block for racing, these pistons are a solid option. Just a heads-up, they are not CARB approved and cannot be shipped to California. Make sure to check the manufacturer's specifications for compatibility with your specific build, especially regarding compression height and pin diameter.
