Wiseco SBC LSX 5.3L 3.79in Bore +6cc Dome 1.321inch CH LEFT Piston Shelf Stock

If you're rebuilding the heart of your LSX 5.3L engine for serious performance, a strong piston is key. This Wiseco Professional Series piston is built for demanding applications where durability and consistent performance are critical. It's forged from 2618 aluminum, which offers improved tensile strength over other aluminum alloys, making it well-suited for heavy-duty use.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features that enhance ring seal. The crown is also fully machined for a clean combustion chamber. A notable feature is the ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. Plus, it includes forced pin oiling to keep the wrist pin well-lubricated under high stress.

This piston is designed to handle severe duty race builds. Keep in mind that this part is not CARB approved and cannot be shipped to California. It's sold individually, so be sure to order the correct quantity for your engine build.
