Wiseco Chevy Big Block 4.560in Bore 1.215in CH 48.70 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components, especially for high-performance applications. This Professional Series piston set is a prime example, designed for serious racers and builders who need parts that can handle extreme conditions. If you're working on a heavy or severe duty race build for your Chevy Big Block, these pistons are engineered to meet those demands.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for better durability under stress. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal, helping to keep combustion where it belongs. You'll also find an ArmorGlide skirt coating, which is designed to resist seizure, reduce friction, and contribute to quieter operation. The fully machined crown and forced pin oiling are further details that show these pistons are built for performance and longevity in demanding race environments.

This set includes eight pistons, each designed for a 4.560-inch bore with a 1.215-inch compression height and a 0.990-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
