If your truck is like mine it has several chips in the paint due to rocks getting flung from the tires and it stays covered in mud due to the mud flung from the tires even after the first time down the road following a good cleaning. After a little research I found the manufacturers of my Husky Liner floor protectors also offered some custom Molded Mud Guards for my truck that not only offered protection but also offer custom good looks.
These Husky Liner Mud Guards are offered in separate front and rear sets so I purchased both front and rear sets to do both ends of my truck. These kits both come with the custom molded guards, all necessary mounting hardware, and installation instructions.
For reference My truck is a 1999 Super Duty with a Rough Country leveling kit and 285/75/16 tires.
