Wiseco Chevy Small Block 4.040in Bore 1.062in CH 13.50 CC Piston Set

This piston set from Wiseco includes eight forged pistons, designed for Chevrolet Small Block engines with a 4.040-inch bore. These are the Professional Series pistons, built for serious racers and builders who need robust components for heavy to severe duty applications. They are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for demanding performance.

You'll find precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The pistons also come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and makes operation quieter. The fully machined crown and forced pin oiling are additional details that contribute to their durability and performance under stress. These are well-built pistons intended to handle the rigors of racing and high-performance builds.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete engine build, you'll want to ensure you have all the necessary supporting components and follow the manufacturer's installation guidelines carefully.
