Wiseco Chevy Big Block 4.310in Bore 1.395in 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 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 stress and heat that comes with it.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for better durability under load. You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal, which is crucial for consistent power and engine health. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling are further details that show these are built for demanding performance.

This set includes eight pistons, each designed for a 4.310-inch bore and featuring a 1.395-inch compression height. The pin diameter is 0.990 inches. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and durability in their Big Block Chevy, this Wiseco set offers a well-built foundation.
