Wiseco Chevy Small Block 4.145in Bore 1.060in CH 12.00 CC Piston Set

If you're rebuilding a high-performance Chevrolet Small Block engine for serious racing, these Wiseco Professional Series pistons are a solid choice. They're designed to handle the intense demands of heavy to severe duty applications, giving you the confidence to push your engine to its limits. Wiseco has packed these pistons with features aimed at both power and durability, making them a go-to for builders who need reliable performance under extreme conditions.

These pistons are forged and machined right here in the USA from 2618 aluminum, which offers improved tensile strength for better resistance to stress and heat. You'll find precision ring grooves, an anti-detonation groove, and other features to enhance ring seal, ensuring your combustion is as efficient as possible. They also come with an ArmorGlide skirt coating, which helps reduce friction and resist seizure, contributing to quieter operation and longer life. The fully machined crown is ready for your build, and forced pin oiling helps keep the wrist pins lubricated under high loads.

This set includes eight pistons, designed for a 4.145-inch bore and featuring a 1.060-inch compression height. Remember that these pistons are not CARB approved and cannot be shipped to California. For a serious build, these Wiseco pistons offer a well-built foundation.
