Wiseco Chevy LS Series -22cc R/Dome 4.155inch Bore Piston Shelf Stock

If you're rebuilding the engine in your performance-oriented GM vehicle, like a Chevrolet Camaro, Pontiac GTO, or Cadillac CTS, these Wiseco pistons are built to handle serious power. These are Professional Series pistons, meaning they're designed for heavy-duty and severe-duty race builds where durability and performance are critical. They feature a -22cc dome shape, which is important for achieving specific compression ratios depending on your cylinder head volume and gasket thickness.

Wiseco forges these pistons from 2618 aluminum right here in the USA, giving them improved tensile strength for high-stress applications. They come with precision ring grooves, an anti-detonation groove, and features to improve ring seal, all contributing to better combustion efficiency and durability. The piston crown is fully machined, and they also include forced pin oiling to keep the wrist pin well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and resist seizure, making for quieter operation and longer life.

This piston is sold individually, so be sure to order the correct quantity for your engine. Keep in mind that these are not CARB approved and cannot be shipped to California.
