Wiseco Chevy Big Block 4.320in Bore 1.395in CH 45.00 CC Piston Set

If you're building a high-performance Chevrolet Big Block engine for serious racing, this Wiseco Professional Series piston set is designed to handle the demands. These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under extreme conditions. Each piston is meticulously crafted with precision ring grooves, anti-detonation features, and additional ring seal enhancements to ensure optimal combustion and durability.

Wiseco includes their ArmorGlide skirt coating, which helps reduce friction and resist seizure, while also contributing to quieter operation. The fully machined crown is ready for your build, and the forced pin oiling system ensures the wrist pin stays well-lubricated, even under heavy loads. This set is built to withstand heavy to severe duty performance applications, making it a solid choice for racers and serious engine builders who push their engines to the limit.

This set includes eight pistons, each designed for a 4.320-inch bore with a 1.395-inch compression height and a 45.00cc combustion chamber volume. Please note that these pistons are not CARB approved and cannot be shipped to California.
