Wiseco Chevy Big Block 4.530in Bore 1.215in CH 40.00 CC Piston Set

If you're building a high-performance Chevrolet Big Block engine, this Wiseco Professional Series piston set is designed to handle the demands of serious racing and severe duty applications. These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for components subjected to extreme stress and heat. The set includes eight pistons, each meticulously crafted to meet the rigorous requirements of performance engine builds.

Wiseco has incorporated several features to enhance both performance and durability. You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal, which is vital for maintaining compression and preventing blow-by. The fully machined crown ensures accurate combustion chamber volume, and the forced pin oiling system helps keep the wrist pins lubricated under high loads. Additionally, these pistons come with an ArmorGlide skirt coating. This coating is designed to reduce friction, resist seizure, and contribute to quieter operation, all while handling the intense conditions found in heavy to severe duty race engines.

This set is specifically designed for a 4.530-inch bore with a 1.215-inch compression height and a 0.990-inch pin diameter. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For builders aiming to push the limits of their Chevrolet Big Block, these Wiseco pistons offer a well-built foundation for a powerful and reliable engine.
