Wiseco Chevy Big Block 4.500in Bore 1.120in 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, built for serious racers and engine builders who demand the best for their Chevy Big Block engines. If you're putting together a heavy-duty or severe-duty race build, these pistons are designed to handle the extreme stresses involved.

These pistons are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for better durability under pressure. You'll find precision ring grooves, an anti-detonation groove, and other features that help improve ring seal for better compression and performance. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown is ready for your build, and forced pin oiling ensures the wrist pins stay well-lubricated.

This set includes eight pistons, each designed for a 4.500-inch bore with a 1.120-inch compression height and a 0.990-inch pin diameter. Keep in mind these are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and reliability in a demanding race application, this Wiseco piston set is a solid choice.
