Wiseco Chevy LS Series -2.8cc Dome 4.155inch Bore Piston Shelf Stock Kit

If you're building a serious performance LS engine, you're probably looking at a set of forged pistons. This kit from Wiseco is designed for those heavy-duty builds where reliability and strength are paramount. These aren't your average pistons; they're crafted from 2618 aluminum, which offers improved tensile strength over other alloys, making them well-suited for the demands of racing and severe duty applications. The -2.8cc dome shape is specific to certain LS engine configurations, helping to achieve a desired compression ratio when paired with the right cylinder heads.

Wiseco puts a lot of thought into the details that matter for longevity and performance. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal and prevent detonation. Plus, the ArmorGlide skirt coating is applied to reduce friction, minimize wear, and help the pistons run quieter. The crown of each piston is fully machined, and they feature forced pin oiling to ensure the wrist pins stay well-lubricated under high stress. This kit is built to withstand the rigors of severe duty performance builds.

This piston set is designed to fit a wide range of popular LS-powered vehicles, including models like the Chevrolet Camaro, Corvette, and Pontiac GTO. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a complete engine build, ensure you have all the necessary supporting components like rings, connecting rods, bearings, and gaskets, as these are typically sold separately.
