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

If you're building or rebuilding a Chevrolet LS engine for heavy-duty performance, these Wiseco pistons are a solid choice. They're forged from 2618 aluminum, which gives them improved tensile strength over cast pistons, making them well-suited for demanding race applications. This specific piston features a -18cc dish, a 4.155-inch bore, and a 1.1105-inch compression height, designed to work with a variety of LS engine configurations.

Wiseco machines these pistons in the USA with precision ring grooves, anti-detonation grooves, and features to improve ring seal. They also come with an ArmorGlide skirt coating that helps reduce friction and noise while resisting seizure. The fully machined crown and forced pin oiling further contribute to their durability and performance in severe duty builds. These pistons fit a range of vehicles, including models like the Cadillac CTS, Chevrolet Camaro, and Pontiac GTO.
