Wiseco Chevy Big Block 4.560in Bore 1.270in CH 15.60 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components, especially for high-performance applications. This Professional Series piston set is a prime example, built for serious racers and builders who need parts that can handle extreme conditions. These pistons are designed for Chevrolet Big Block engines and are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for demanding builds.

You'll find a lot of attention to detail here. The precision ring grooves, anti-detonation grooves, and other features are there to improve ring seal and overall performance. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling are features you'd expect in a top-tier racing piston, all designed to help your engine withstand heavy to severe duty performance applications. This set includes 8 pistons, ready for your next build.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For your build, you'll want to ensure you have the correct supporting components like connecting rods and a crankshaft that match the 4.560 inch bore and 1.270 inch compression height.
