Wiseco Chevrolet LS 4.030in Bore 1.304in CH -3.20 CC Professional 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 the best for their Chevrolet LS engine. If you're rebuilding the top end of your 1997-2004 Corvette, or a compatible Camaro, Firebird, or GTO, these pistons are built to handle the stress of heavy to severe duty race builds.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for durability under extreme conditions. Wiseco has included several features to enhance performance and longevity, such as precision ring grooves, an anti-detonation groove, and other features that improve ring seal. The fully machined crown ensures accuracy, and forced pin oiling helps keep the wrist pins lubricated. They also come with an ArmorGlide skirt coating that helps reduce friction, makes operation quieter, and resists seizure.

This set includes eight pistons, each with a 4.030-inch bore and a 1.304-inch compression height. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For optimal installation, always refer to the manufacturer's detailed instructions.
