Wiseco Chevrolet LT1 6.2L 4.075 Bore 3.622 Stroke 6.125 Rod -2cc Volume 1.304 Comp Height

Forged from 2618 aluminum, these Wiseco Professional Series pistons are built for the demands of severe duty race applications in Chevrolet LT1 6.2L engines. The material choice here is key; 2618 aluminum offers improved tensile strength over other alloys, which is crucial when you're pushing an engine hard. This set is designed for a 4.075 inch bore with a 3.622 inch stroke, and features a -2cc volume in the piston crown, contributing to your compression ratio calculations.

Wiseco machines these pistons in the USA, ensuring precision throughout the manufacturing process. You'll find features like precision ring grooves, anti-detonation grooves, and additional ring seal improvements designed to keep combustion gases contained and power where it belongs. The piston crown is also fully machined for consistency. A notable feature is the ArmorGlide skirt coating, which helps reduce friction for quieter operation and resistance to seizure, a common concern in high-performance builds.

This set includes forced pin oiling to ensure the wrist pins stay well-lubricated under high stress. Remember that these pistons are not CARB approved and cannot be shipped to California. If you're building a serious race engine and need pistons that can handle heavy to severe duty, this Wiseco set is a well-built option designed for that purpose.
