Stock mirrors on S-Series platform trucks suck. They're just big and stupid, but they do fold in to protect themselves from getting banged up by idiot drivers, but if they weren't so damn huge in the first place, they wouldn't even need to fold in. Total failure. Good thing Street Scene Equipment's Cal-Vu mirrors are easy to install and are just plain sexy. Plus, they are available with factory power and fancy LED turn signal options. Best of all, these little gems install easily and painlessly.
