Wiseco Chevy LS Series -3cc Dome 4.065inch Bore Piston Shelf Stock

This Wiseco piston is forged from 2618 aluminum, a material chosen for its improved tensile strength, making it well-suited for demanding engine builds. It features a -3cc dome and a 4.065 inch bore, designed to work within the Chevrolet LS engine platform. The precision machining includes anti-detonation grooves and features aimed at improving ring seal, which are critical for consistent performance under stress.

Wiseco has applied an ArmorGlide skirt coating to this piston. This coating helps reduce friction, resist seizure, and contribute to quieter operation, all important factors when building a performance engine that needs to hold up to severe duty. The crown is also fully machined, and the design incorporates forced pin oiling to ensure the piston pin receives adequate lubrication.

This piston is intended for serious racers and builders looking for durability in heavy to severe duty applications. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to manufacturer installation instructions for proper fitment and assembly procedures.
