Wiseco Chevy LT1 4.065in Bore 1.105in CH -20.00 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components, especially for performance applications. This Professional Series piston set is built for serious Chevy LT1 engine builders who demand top performance and durability. These aren't your average pistons; they're designed to handle the stress of heavy to severe duty racing builds, giving you the confidence to push your engine's limits.

Each piston starts as a forging from 2618 aluminum, chosen for its improved tensile strength, making these pistons well-built for high-stress environments. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The crown is fully machined for accuracy, and they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. Plus, forced pin oiling ensures the wrist pin stays well-lubricated under demanding conditions.

This set includes eight pistons, each with a 4.065-inch bore, a 1.105-inch compression height, and a -20.00cc dish volume. The wrist pin diameter is 0.927 inches. Please note that these pistons are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and reliability in their LT1 engine, this Wiseco set is a solid option.
