Wiseco Chevy Small Block 4.135in Bore 1.000in CH 3.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston set is built for serious racers and builders who need parts that can handle heavy to severe duty use. These pistons are designed to remove limits in demanding race builds.

Each piston in this set is forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for high-stress environments. They feature precision ring grooves, anti-detonation grooves, and other features to improve ring seal. The crown is fully machined, and they include forced pin oiling for better lubrication. Plus, they come with an ArmorGlide skirt coating that helps resist seizure, reduces friction, and makes operation quieter.

This set includes eight pistons, each designed for a 4.135-inch bore with a 1.000-inch compression height and a 0.927-inch pin diameter. Keep in mind these are not CARB approved and cannot be shipped to California.
