Wiseco Chevy Small Block 4.125in Bore 1.060in CH 12.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built with improved tensile strength to handle the demands of serious racing and severe duty applications. The 4.125 inch bore size is a common upgrade for Chevy small block engines looking to increase displacement and power.

Each piston features precision machined ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The crown is also fully machined, and the pistons include forced pin oiling to ensure proper lubrication. Wiseco also applies an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation.

This set includes eight pistons, designed for a 1.060 inch compression height and a 0.927 inch pin diameter. They are engineered and machined in the USA, reflecting Wiseco's commitment to performance and durability for builders who push their engines to the limit.
