Good protection. However, as I have seen, some assembly tips refer to the supplied screws as "junk". The screws are not a problem, this is the recommended drill bit size in the manufacturer's specs. Being familiar with metalworking and fabrication, I immediately found that the recommended 1/8" drill bit size is too small for the screws provided. The ideal pilot drill size is 5/32". Be sure to. Don't use unnecessary self-tapping screws in your closet or trash can as they don't look as good and can vibrate loose over time. If you do not have a 90Β° drill/screwdriver, you MUST remove the back of the wheel to install. Easy enough with a jack. Follow the instructions at this stage and the installation will be perfect. Replace wheels and recheck nuts after torque drive if you have aluminum wheels. For the front it was much easier. Start the truck and turn the wheel so the side you want to work on is facing out. Follow the instructions for this step. HOWEVER, note that the LOWER hole has multiple layers of material and a self-tapping screw in the fender. If you are not careful, the center drills in the lower openings of the facades can easily break. I lost a bit to the brackets on each side but in the end it didn't affect the installation and only now the bit tips are floating somewhere in the fenders haha. They look like OEM. This is no ordinary plastic, but a durable polymer with a decent texture. I had to use a razor to trim off the burrs on the edges as they weren't factory cleaned. I haven't had them long, but I live on a rough dirt road and have blocked rockfalls well so far. I have them on a 2013 F150 FX4 with factory footpegs/nerfs and plenty of room regardless of the description and have OEM fender flares. They will not work with fiberglass pegs that are in a closed housing, nor will they work with wheel-to-wheel landing gear. Not recommended for lifted trucks with large tires as they won't block much. If I can add photos later, I will. I hope these tips help, drill bit size is the largest. All four only took me 20 minutes.
