Wiseco Chevy Small Block 4.030in Bore 1.125in CH -1.70 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 4.030-inch bore. If you're building a serious performance engine that needs to handle heavy or severe duty, these pistons are designed to meet that challenge.

These pistons are forged and machined right here 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 and resist seizure, while also making operation quieter. The fully machined crown is ready for your build, and forced pin oiling helps keep things lubricated.

This set includes eight pistons, designed for a 1.125-inch compression height and a 0.927-inch pin diameter. Keep in mind these are not CARB approved and cannot be shipped to California. They are intended for serious racers and builders who need robust internal engine parts.
