Wiseco Chevy LS Series -20cc R/Dome 1.110x4.080 Piston Shelf Stock Kit

If you're building a high-performance Chevy LS engine for serious racing or heavy-duty use, this Wiseco Professional Series piston set is a solid choice. These pistons are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for demanding applications. The -20cc R/Dome design is specific to certain LS engine configurations, and the 4.080-inch bore size is a common upgrade for increased displacement.

Wiseco has packed these pistons with features to ensure durability and performance under extreme conditions. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. The pistons also come with forced pin oiling to keep the wrist pins lubricated, and the crown is fully machined for accuracy. A notable feature is the ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly, even under severe duty.

This set includes eight pistons, designed to meet the challenges of heavy to severe duty race builds. While these pistons are built for performance, please note they are not CARB approved and cannot be shipped to California. They are intended for off-road or racing applications where maximum power and durability are critical.
