All 2018-2026 Silverado 1500, Sierra 1500; and 2019-2026 Silverado 2500HD/3500HD and Sierra 2500HD/3500HD trucks have stone guard protection applied to the lower painted surfaces that provides added defense against stone chips and road debris to help keep the vehicle exterior looking good. (Fig. 13) For trucks built at the Oshawa assembly plant (11th VIN position – 1), there may be some customer concerns about the lack of an anti-chip coating on the exterior of the trucks.
Fig. 13
Trucks built at the Flint, Fort Wayne, and Silao assembly plants feature stone guard protection along the lower painted surfaces that have a textured appearance, which provides a visible indication of the stone guard application.
However, trucks that are built at the Oshawa assembly plant go through a powder anti-chip material process for stone guard protection that does not have a textured appearance. The anti-chip performance meets all engineering criteria for durability and quality without a visibly textured surface.
No repairs should be performed and no additional applications of any anti-chip coatings should be applied.
