Awesome product!
These were very easy to install, match the black OEM fender flares great and look awesome as well.  The best part is they allow for 35” tires when installing a 3” leveling kit.

I recently ordered a 6 piece mud flap delete kit. It was easy to get the parts specific to my truck and check out. I received my order faster than expected, which is always nice.

The parts arrived well packaged, individually wrapped, with directions.

Overall install took approximately 1 hour for all 6 caps.

There is no cutting. They are 100% no drill and fasten directly to the truck using existing holes

The Finishing Caps are also designed to allow installation of Truck Hardware Gatorback mud flaps.
