If you're building or rebuilding a Chevrolet LS engine for serious performance, this Wiseco forged piston is a solid option. It's designed to handle the demands of heavy to severe duty applications, offering improved strength and durability over stock cast pistons. This specific piston has a 4.130-inch bore and a -1cc dish volume, which is important for setting your compression ratio. It also features a 1.2995-inch compression height and a 0.927-inch pin diameter, critical measurements for proper engine assembly.

Wiseco makes these pistons in the USA from 2618 aluminum, a material known for its high tensile strength, making them well-suited for racing and high-stress builds. You'll find precision ring grooves, an anti-detonation groove, and features designed for better ring seal. The piston crown is fully machined, and it includes forced pin oiling for better lubrication. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure.

This piston fits a wide range of GM vehicles with LS engines, including models like the Chevrolet Camaro, Corvette, and Cadillac CTS. It's a component designed for builders who want reliable performance under tough conditions.
