Wiseco Chevy Big Block 4.500in Bore 1.215in CH 48.70 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 need top-tier performance and durability in their Chevy Big Block engines. These aren't just any pistons; they're built from the ground up to handle the demands of heavy to severe duty race builds, giving you the confidence to push your engine's limits.

Each piston in this set is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for withstanding the intense pressures and heat inside a performance engine. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, ensuring efficient combustion and preventing detonation. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. The fully machined crown is another detail that speaks to the care taken in their construction, ensuring consistent performance across the set.

This set includes everything you need for an 8-cylinder engine, with a 4.500-inch bore and a 1.215-inch compression height. The forced pin oiling feature ensures the wrist pin stays well-lubricated, a critical detail for longevity in high-stress applications. While these pistons are built for extreme performance, please note they are not CARB approved and cannot be shipped to California.
