Wiseco Chevy LT1 4.075in Bore 1.105in CH -10.00 CC Piston Set

Wiseco's Professional Series forged pistons are built for serious racers and builders working on Chevrolet LT1 engines. These pistons are designed to handle heavy to severe duty performance applications, offering a significant step up from stock components. They are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for high-stress engine builds.

You'll find precision ring grooves, anti-detonation grooves, and features aimed at improving ring seal, all contributing to better combustion control and durability. The pistons also come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and operate more quietly, which is a notable benefit in high-performance engines where heat and stress are extreme. The fully machined crown ensures accuracy and consistency across the set.

This set includes eight pistons, each with a 4.075-inch bore, a 1.105-inch compression height, and a -10.00cc dish volume. They also feature forced pin oiling for enhanced lubrication of the wrist pin. Please note that these pistons are not CARB approved and cannot be shipped to California.
