Wiseco Chevy Big Block 4.500in Bore 1.270in CH -19.00 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, designed for serious racers and builders who demand the best for their Chevy Big Block engines. These aren't just any pistons; they're built from the ground up to handle the intense pressures and heat found in heavy to severe duty race builds, pushing the limits of what your engine can do.

Each piston in this set is forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength to withstand extreme conditions. You'll find precision ring grooves, an anti-detonation groove, and other features specifically designed to improve ring seal, meaning better compression and more power. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly, even under heavy load. The fully machined crown ensures accuracy and consistency across the set, and forced pin oiling helps keep the wrist pins properly lubricated for long life.

This set includes eight pistons, each designed for a 4.500-inch bore with a 1.270-inch compression height and a -19.00cc dish. While these pistons are built for extreme performance, please note they are not CARB approved and cannot be shipped to California. If you're building a high-performance Chevy Big Block and need pistons that can take a beating and keep performing, this Wiseco set is a solid option.
