Truck Hardware Finishing Caps allow you to replace the integrated OEM molded splash guards with a cap that maintains the OEM appearance. The Finishing Caps are also designed to support and enhance the installation of Truck Hardware Gatorback CR Series mudflaps.
The OEM splash guards were designed around the OEM fender flares, which made it impossible to remove the OEM splash guards, without leaving the end of the flares open and unfinished. The OEM splash guards also prevented installing the Gatorback mudflaps properly. The Finishing Caps solve this problem.
