Wiseco Chevy SB -32cc Dome 4.125in Bore Piston Shelf Stock Kit

These Wiseco pistons start with a -32cc dome and are forged from 2618 aluminum, a material chosen for its improved tensile strength, making them a solid choice for demanding engine builds. Designed for Chevrolet Small Block engines with a 4.125-inch bore, this set is built to handle heavy to severe duty performance applications where reliability is paramount.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal. The crown is fully machined for accuracy, and the piston skirts are treated with an ArmorGlide coating. This coating is designed to resist seizure, reduce friction, and contribute to quieter operation, all important factors when pushing an engine hard. The forced pin oiling system ensures the wrist pin receives adequate lubrication, a critical detail for longevity under stress.

This is a set of 8 pistons, intended for builders who are serious about performance and durability. Keep in mind these pistons are not CARB approved and cannot be shipped to California. For a complete build, ensure you have the correct supporting components like connecting rods, rings, and bearings that match the 4.125-inch bore and 0.927-inch pin diameter.
