Wiseco Chevy Small Block 4.040in Bore 1.125in CH -5.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for 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 in this set is forged and machined in the USA from 2618 aluminum, which gives 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 that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling are details that show these pistons are made for serious performance and durability.

This set includes eight pistons, each with a 1.125-inch compression height and a -5.00cc dish volume. Remember, these are not CARB approved and cannot be shipped to California. If you're building a high-performance Chevy Small Block and need pistons that can handle the stress, this Wiseco set is a solid option.
