Wiseco Chevy LS Series -20cc R/Dome 1.110x4.075 Piston Kit

Wiseco is well-known for making strong, reliable internal engine components, especially for high-performance applications. This Professional Series piston kit for Chevy LS engines is a prime example of their commitment to serious builders. These aren't your average pistons; they're forged from 2618 aluminum right here in the USA, giving them improved tensile strength needed for the demands of heavy to severe duty race builds. If you're putting together a high-performance LS engine, these pistons are built to handle the stress.

What sets these pistons apart is the attention to detail in their design and machining. You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal. They also come with an ArmorGlide skirt coating, which helps reduce friction and resist seizure, all while keeping operation quieter. The fully machined crown ensures everything is just right for optimal combustion. Plus, the forced pin oiling helps keep the wrist pins lubricated under extreme conditions, a critical factor for engine longevity in performance builds.

This kit includes everything you need for a set of 8 pistons, each with a -20cc dome volume and designed for a 4.075-inch bore. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are intended for serious racers and builders who need components that can withstand extreme use.
