Wiseco Chevy LT1 4.075in Bore 1.105in CH -20.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for high-performance applications. This Professional Series piston set is a prime example, designed for serious racers and builders who demand top-tier performance and durability from their Chevy LT1 engines. These aren't just any pistons; they are built with no-expense-spared features to handle the rigors of heavy to severe duty race builds, helping you 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 under extreme conditions. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, ensuring efficient combustion and preventing detonation. The crown is fully machined for accuracy, and they feature forced pin oiling to keep the wrist pins well-lubricated. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, contributing to overall engine health and performance.

This set includes eight pistons, each with a 4.075-inch bore, a 1.105-inch compression height, and a -20.00cc dish volume, designed to work with a 0.927-inch pin diameter. These pistons are engineered and built to withstand the demands of competitive racing and high-stress performance applications. Please note that this part is not CARB approved and cannot be shipped to California.
