J.C. Whitney GC07580034 Active Grille Shutter OEM Replacement for Canyon & Colorado

The J.C. Whitney GC07580034 is an OEM-replacement active grille shutter assembly designed for the 2015–2022 GMC Canyon and 2015–2022 Chevrolet Colorado. This unit replaces GM OEM part number 23178140 and restores the factory aerodynamic and thermal management system to like-new performance.

Active grille shutters (also called radiator shutters or grille air shutters) automatically open and close to regulate airflow through the front grille. At highway speeds, the shutters close to reduce aerodynamic drag and improve fuel economy. At lower speeds or under heavy load, they open to allow maximum airflow to the radiator and engine bay for optimal cooling.

Key Features:

• Direct OEM replacement — matches factory fit, form, and function
• Replaces GM OEM part number 23178140
• Compatible with 2015–2022 GMC Canyon and 2015–2022 Chevrolet Colorado
• Shutter assembly only — does not include actuator motor or actuator
• Restores factory aerodynamic efficiency and engine cooling regulation
• Designed for straightforward, no-modification installation using factory mounting points

This replacement shutter assembly is ideal for vehicles with broken, cracked, or malfunctioning grille shutters. Note that this part ships without an actuator or actuator motor — reuse your existing actuator components or source them separately if required.
