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

If you're building a serious performance LS engine, these Wiseco Professional Series pistons are a solid choice. They're designed for heavy-duty race applications, meaning they're built to handle a lot of stress and power. This kit includes everything you need for an 8-cylinder engine, with pistons featuring a -22cc dome and a 4.155-inch bore, which is a common size for many LS engine builds.

Wiseco forges these pistons from 2618 aluminum right here in the USA. This material is known for its improved tensile strength, which is crucial when you're pushing an engine hard. They also come with precision-machined ring grooves, anti-detonation grooves, and features designed to improve ring seal, all contributing to better performance and durability. The pistons also have a special ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and makes the engine run quieter, which is a notable benefit in high-performance builds.

The crown of each piston is fully machined, and they feature forced pin oiling to ensure the wrist pins stay well-lubricated under extreme conditions. These pistons are designed to fit a range of popular GM vehicles with LS engines, including models like the Chevrolet Corvette, Camaro, and Pontiac GTO. Keep in mind these are intended for racing and performance builds and are not CARB approved, so they cannot be shipped to California.
