Wiseco Chevy LS Series -20cc R/Dome 4.125inch Bore Piston Shelf Stock Kit

Wiseco has a long history of building tough engine components, and their Professional Series pistons are a prime example of that dedication. If you're building a serious performance engine for your Chevrolet LS, these pistons are designed to handle some serious punishment. They're forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength over other materials, making them well-suited for heavy-duty and severe-duty applications.

What sets these pistons apart is the attention to detail. You'll find precision ring grooves, an anti-detonation groove, and other features that help improve ring seal, which is crucial for getting the most power and efficiency out of your engine. They also come with an ArmorGlide skirt coating. This isn't just for looks; it helps reduce friction, makes operation quieter, and resists seizure, all contributing to a longer-lasting, more reliable engine under demanding conditions. The fully machined crown and forced pin oiling further demonstrate that these are built for performance.

This kit includes a set of eight pistons, each featuring a -20cc dome volume and a 4.125-inch bore diameter, designed to fit a range of popular LS-powered vehicles like the Chevrolet Camaro, Corvette, and Pontiac Firebird. While these are built for extreme performance, please note they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
