Wiseco Chevy Small Block 4.040in Bore 1.125in CH -19.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for high-performance applications. This Professional Series piston set is a prime example, built for Chevy Small Block engines with a 4.040-inch bore. These aren't your average pistons; they're designed for serious racers and builders who push their engines hard, handling heavy to severe duty performance builds.

Each piston is forged and machined in the USA from 2618 aluminum, giving them improved tensile strength for demanding conditions. You'll find precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal. They also come with an ArmorGlide skirt coating, which helps reduce friction and noise while resisting seizure. The fully machined crown and forced pin oiling further contribute to their durability and performance under stress.

This set includes eight pistons, ready to be installed in your engine. Keep in mind these are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and reliability in a tough application, these Wiseco pistons are a solid choice.
