Wiseco Chevy Big Block 4.605in Bore 1.270in CH 45.00 CC Piston Set

Wiseco is well-known for making strong, reliable engine components, especially for high-performance applications. This Professional Series piston set is a prime example, built for serious racers and builders who need dependable parts for heavy to severe duty race builds. These pistons are designed to handle the demands of competitive engines, giving you the confidence to push your build to its limits.

Each piston in this set is forged and machined in the USA from 2618 aluminum, chosen for its improved tensile strength under extreme conditions. You'll find precision ring grooves, anti-detonation grooves, and other features that help improve ring seal for better combustion efficiency. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown ensures accuracy and consistency across the set.

This set is specifically for Chevrolet Big Block engines with a 4.605-inch bore and a 1.270-inch compression height. The forced pin oiling feature helps keep the wrist pins lubricated, which is crucial for longevity in high-stress applications. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, ensure you have all necessary supporting components and refer to manufacturer instructions for proper installation.
