Wiseco Chevy Small Block 4.035in Bore 1.125in CH -1.70 CC Piston Set

This Wiseco Professional Series piston set includes eight forged pistons, ready to be installed in your Chevrolet Small Block engine. Each piston is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, making these pistons well-suited for demanding race applications. The pistons feature a 4.035-inch bore and a 1.125-inch compression height, with a -1.70cc valve relief volume.

Wiseco has packed these pistons with features for serious builders. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The fully machined crown ensures accuracy, and forced pin oiling helps keep the wrist pins lubricated under high stress. Additionally, these pistons come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. These are built to withstand heavy to severe duty performance builds.

Please note that this piston set is not CARB approved and cannot be shipped to California. It's recommended to consult your engine builder or a professional mechanic for specific installation requirements and compatibility with your build.
