Wiseco Chevy LS Series -25cc Dish 4.070inch bore Piston Shelf Stock

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance builds. The -25cc dish design and 4.070-inch bore are key specifications for engines needing a specific compression ratio and displacement, common in performance LS engine builds for vehicles like the 1997-2004 Chevrolet Corvette, 1998-2002 Camaro, 1998-2002 Firebird, and 2004 GTO.

Wiseco's Professional Series pistons are designed to handle heavy to severe duty applications. They feature precision ring grooves, an anti-detonation groove, and additional features to improve ring seal. The crown is fully machined, and the piston pin features forced oiling to ensure proper lubrication. For added durability and reduced friction, these pistons also come with an ArmorGlide skirt coating, which helps resist seizure and operate more quietly.

This is a single piston, so be sure to order the correct quantity for your engine build. Please note that this part is not CARB approved and cannot be shipped to California.
