Wiseco Chevy LT1 4.125in Bore 1.115in CH -6.90 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components, especially for high-performance applications. This Professional Series piston set is built for serious racers and builders who need parts that can handle extreme conditions. These pistons are designed for Chevrolet LT1 engines and feature a 4.125-inch bore size, a 1.115-inch compression height, and a -6.90cc dish volume, which is important for setting your compression ratio.

Each piston is forged and machined in the USA from 2618 aluminum, chosen for its improved tensile strength under high stress. They come with precision ring grooves, anti-detonation grooves, and other features to improve ring seal. The pistons also have an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown ensures accuracy, and forced pin oiling helps keep the wrist pins lubricated under heavy loads, making these pistons ready for severe duty performance builds.

This set includes eight pistons, enough for a complete V8 engine. 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 details.
