Wiseco Chevy LS Series -18cc R/Dome 4.155inch Bore Piston Shelf Stock

If you're rebuilding or upgrading a Chevrolet LS engine for heavy-duty performance, a strong set of pistons is crucial. This Wiseco Professional Series piston is built from 2618 aluminum, a material known for its improved tensile strength, making it a solid choice for demanding race builds. The -18cc dish design is specifically for certain LS engine configurations, helping to achieve your target compression ratio.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves and anti-detonation features to ensure a good seal and prevent issues under high stress. The ArmorGlide skirt coating is a notable addition; it helps reduce friction for smoother operation and also resists seizure, which is important when an engine is pushed hard. Forced pin oiling is included to keep the wrist pin well-lubricated, further enhancing durability in severe duty applications.

This piston is designed to fit a range of popular LS-powered vehicles, including models like the Cadillac CTS, Chevrolet Camaro, and Pontiac Firebird. It's a well-made component intended for builders who need reliable performance from their engine's core components.
