Listed at 49.99 USD. 2007-2013 Silverado/Sierra Mirror Cap Overlays Shellz are easy to install, durable, custom fit covers designed to overlay your factory body panels. Shellz are the go-to solution for getting rid of chrome, blacking out, or color matching body panels and trim. They are much more durable than paint or vinyl, meaning they have a secondary use as an extra durable protection for your bumper from stone chips and debris. As well as adding protection, Shellz are a much more economical cosmetic alternative to dent repair or OE replacement parts. They come in a variety of colors including Gloss Black, Gloss White, and a high quality Matte Black that can also be painted to match your vehicle. Shellz can be installed with a few simple hand tools with most installs taking around 30 minutes.
