Wiseco Chevrolet Big Block Piston Set 4.280in Bore 1.760in. CH 0.990in. Pin Dia. - Set of 8

Wiseco is well-known for making strong, reliable internal engine components, especially for high-performance applications. This Professional Series piston set is built for Chevrolet Big Block engines and is designed for serious racers and builders who need parts that can handle extreme conditions. These aren't your average pistons; they're crafted from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial when you're pushing an engine hard.

Each piston in this set features precision ring grooves, an anti-detonation groove, and other features to improve ring seal, ensuring efficient combustion and durability. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown is ready for whatever you throw at it, and the forced pin oiling system ensures the wrist pin stays well-lubricated. These pistons are designed and built to withstand heavy to severe duty performance applications, meaning they're ready for demanding race builds.

This set includes eight pistons, each with a 4.280-inch bore, a 1.760-inch compression height, and a 0.990-inch pin diameter. When rebuilding or modifying your engine for serious performance, these Wiseco pistons are a solid option to consider for their robust construction and race-ready features. Please note that these pistons are not CARB approved and cannot be shipped to California.
