Wiseco Chevy LS Series -20cc R/Dome 1.110 CH 4.020in Bore Piston Shelf Stock Kit

Forged from 2618 aluminum right here in the USA, these Wiseco pistons are built for serious engine work. They feature a -20cc reverse dome design and a 4.020-inch bore, making them a solid choice for rebuilding or upgrading your Chevrolet LS engine. The 1.110-inch compression height and 0.927-inch pin diameter are standard for many LS applications, ensuring a good fit when you're putting together a performance package.

Wiseco packs these Professional Series pistons with features aimed at durability and performance under demanding conditions. You'll find precision-machined ring grooves, anti-detonation grooves, and other features designed to improve ring seal. The crown is fully machined for a clean finish, and they come with forced pin oiling to keep things well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also resisting seizure, which is crucial when you're pushing an engine hard.

This kit includes a set of eight pistons, along with premium rings, ready for installation in your 1997-2004 Chevrolet Corvette, or compatible Camaro, Firebird, or GTO models. Keep in mind these are not CARB approved and cannot be shipped to California. For builders aiming for heavy to severe duty performance, these pistons are designed to handle the stress.
