Wiseco Chevy Big Block 4.350in Bore 1.395in CH 45.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built with improved tensile strength to handle the demands of severe duty racing applications. The 4.350-inch bore size is specific for Chevy Big Block engines, and each piston features a 1.395-inch compression height. Wiseco machines these pistons in the USA, ensuring precision throughout the manufacturing process.

You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is critical for performance and longevity under high stress. The fully machined crown is ready for your build, and forced pin oiling helps keep the wrist pin lubricated. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and contribute to quieter operation, making these pistons a solid choice for serious racers and builders looking to push their engines to the limit.

This set includes eight pistons, designed for heavy to severe duty performance builds. Please note that these pistons are not CARB approved and cannot be shipped to California.
