Wiseco Chevy LT1 4.065in Bore 1.105in CH -15.00 CC Piston Set

Wiseco's Professional Series piston set is built for serious performance applications in Chevrolet LT1 engines. These pistons are designed for a 4.065 inch bore and feature a 1.105 inch compression height, with a 0.927 inch pin diameter. They are engineered and forged in the USA from 2618 aluminum, a material chosen for its improved tensile strength, making these pistons well-suited for heavy to severe duty racing builds.

You'll find precision in the ring grooves, anti-detonation features, and additional ring seal improvements, all aimed at maximizing performance and durability under extreme conditions. The fully machined crown ensures accuracy, and forced pin oiling helps keep the pins lubricated. Additionally, these pistons come with an ArmorGlide skirt coating, which helps resist seizure, reduces friction, and contributes to quieter operation. This set is designed to help you push the limits in your performance build.

This set includes eight pistons. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
