Wiseco Chevy LS Series -22cc R/Dome 4.125inch Bore Piston Shelf Stock

Forged from 2618 aluminum, these Wiseco pistons are built for serious LS engine builds. The -22cc dome volume is a specific design choice that impacts compression ratio, making them suitable for certain performance applications where precise control is needed. They feature a 4.125-inch bore and a 1.0505-inch compression height, with a 0.927-inch pin diameter. This piston is designed to withstand heavy to severe duty performance use, offering improved tensile strength and durability.

Wiseco includes several features to enhance performance and longevity. The piston crown is fully machined, and the ring grooves are precision-machined with additional features for improved ring seal. An ArmorGlide skirt coating is applied to reduce friction, resist seizure, and contribute to quieter operation. Forced pin oiling is also incorporated to ensure proper lubrication of the wrist pin.

These pistons are intended for builders who need robust components for demanding LS engine projects. They fit a range of GM vehicles, including models like the Cadillac CTS, Chevrolet Camaro, and Pontiac GTO, among others. Remember that these are not CARB approved and cannot be shipped to California.
