Wiseco Chevy LS Series -20cc R/Dome 1.110x4.005 Piston Shelf Stock

If you're rebuilding the engine in your 1997-2004 Chevrolet Corvette for serious performance, a strong set of pistons is key. These Wiseco Professional Series pistons are built from 2618 aluminum, which offers improved tensile strength for demanding applications. They feature a -20cc dish, a 4.005 inch bore, and a 1.1105 inch compression height, designed to work with your LS series engine.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features that improve ring seal. They also come with an ArmorGlide skirt coating that helps reduce friction and noise, while also resisting seizure. The crown is fully machined, and the pin bores are set up for forced oiling to keep things well-lubricated under stress.

These pistons are intended for heavy to severe duty builds where durability and performance are critical. Keep in mind these are not CARB approved and cannot be shipped to California.
