So I am thinking about adding some Shrockworks sliders to my Fronty for a more finished look. In addition it would make it a little easier for my gf getting in and out of the truck. I don't want side steps since they stick out a lot and I lose ground clearance. The Shrockworks sliders look nice, I am wondering how easy are they to install? Is is simply bolt-on? The website mentions drilling but I just wanted to ask here first. Is the 3rd support option recommended? Thanks in advance.
