Wiseco Chevy LS Series -2.8cc Dome 4.200inch Bore Piston Shelf Stock Kit

Wiseco is well-known for making strong, reliable internal engine components, especially for high-performance applications. This Professional Series piston kit is a prime example, designed for builders who are serious about getting the most out of their LS engine. These aren't your average pistons; they're built from the ground up for heavy to severe duty race builds where durability and performance are critical.

Each piston in this set is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under extreme conditions. You'll find precision ring grooves, anti-detonation grooves, and other features designed to enhance ring seal, which is crucial for maintaining compression and preventing blow-by. The fully machined crown ensures accuracy, and forced pin oiling helps keep the wrist pins lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, even under intense heat and load.

This kit includes everything you need to outfit an 8-cylinder LS engine with a 4.200-inch bore. It's a solid option if you're rebuilding your top end for serious performance and need components that can handle the stress of racing or demanding street use. Just remember, these pistons are not CARB approved and cannot be shipped to California.
