Wiseco Chevy LS Series -23cc R/Dome 4.125inch Bore Piston Shelf Stock Kit

When you're building a serious performance LS engine, especially for racing or heavy-duty use, the pistons are a critical component. This Wiseco Professional Series piston kit is built from the ground up for those demanding applications. They're made from 2618 aluminum, which is well-known for its high tensile strength, making these pistons a solid choice for high-stress environments.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. This helps ensure efficient combustion and keeps blow-by to a minimum. The crown of each piston is fully machined, and they also feature forced pin oiling to keep the wrist pins well-lubricated under extreme conditions. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which is a nice benefit even in a race engine.

This kit is designed for a 4.125-inch bore and features a -23cc dome, which is a specific volume that affects compression ratio depending on your cylinder head volume. It's important to note that these pistons are not CARB approved and cannot be shipped to California. This set includes pistons for an 8-cylinder engine, and you'll want to consult the manufacturer's instructions for the full list of included components and any specific installation requirements.
