Wiseco K0379XS Gen V Forged Piston Kit Bore Dish - L83 5.3L 3.780 0.5cc

The Wiseco K0379XS is a Professional Series forged piston kit engineered specifically for the GM Gen V Direct Injected L83 5.3L EcoTec3 engine platform. Designed for high-performance street and race builds, this kit features a 3.780-inch bore with a -0.5cc dish crown, delivering a 10.5:1 compression ratio with a standard 58cc chamber — ideal for naturally aspirated and mildly boosted applications.

Each piston is forged and machined in the USA from 2618 high-strength aluminum alloy, providing the superior tensile strength and thermal resistance required for demanding performance use. The kit includes Wiseco's renowned ArmorGlide skirt coating, a permanent dry-film lubricant that reduces friction, resists seizure, and contributes to quieter piston operation throughout the life of the part.
