Glass

Find New OEM glass components and related seals for GM vehicles. Our factory-original window glass is sourced from GM surplus — the correct tint grade, solar reflectivity, heating element configuration, and antenna element pattern for your specific application.

OEM glass is manufactured to the exact curvature and edge profile of your vehicle's opening — ensuring a proper seal and correct aerodynamic performance. Aftermarket glass frequently exhibits optical distortion, incorrect tint grade, and heating element failures due to inferior manufacturing processes.

Verify glass specifications against your vehicle's glass option codes (heated rear glass, privacy glass, solar control glass) before ordering. Contact us for fitment assistance.
