Finishing caps
Had to remove the mud shields on my 2019 GMC 1500 to run 35” tires. Unfortunately when the shields are removed it leaves an unsightly hole in the fender and looks unfinished. These finishing caps were the perfect way to complete the plastic molding around the fender wells.

The Best solution for a lifted 2019 GMC
Had to remove the front splash guards to run 35’s on my lifted 2019 GMC.  Most trucks have the bottom half of the splash guard hacked off to run the larger tires. These are a cleaner and better way to finish off your lifted truck.

Great quality, easy to install
I looked everywhere for something like this so I could take the factory mudflats off of my new truck.  I finally found them, ordered them, and when they arrived I was impressed by their quality.  I watch the videos on YouTube before installing and had no problems getting the old off and the new ones on.

Fits perfect, color is exactly the same. Definitely worth the money and the looks speak for itself.

I am not sure if that would work. That fitment was not tried. They are working on the front replacements as well. The 4 needed to be finished to allow for aftermarket flap installation.

They will not. The caps are designed specifically for the Sierra. The Sierra slash guards when removed leave a large gap to fill. The Silverado doesn't have that issue. But I would love to get you in some of the Gatorback no drill flaps. :)

No, there are no plans for color matched caps. These are a paintable product though.

If you want to take off the factory integrated mud flaps off the new GMC Sierra 1500 there will now be a missing section to the fender flare/trim.

These caps are custom designed to fill that section. They are made of the same material and have the same finish and texture. They will give a seamless look without the mud flaps.
