I chose these because I have a Rock Hard rear bumper and really like it. At $299 they are priced great. And you also get side tubes and powder coating in that price. They are 3/16" thick. I know there are stronger rocker guards out there. I'm not worried since I'm not doing anything crazy. I like the look and price.
I purchased them from 4WheelParts because there is a location in Colorado that is close to were I live. I like doing face-to-face business when feasible. When I opened the packaging I noticed the hardware was missing. I called Rock Hard and they sent some out really quick. It took just a few days! It's stainless steel, you even get a few extra bolts (maybe those extra bolts are for the longer LJ sliders). The powder coating was damaged in a few areas. I painted the scratches and it looks fine.
Rock Hard recommends a bead of silicone on the top edge of the sliders, but I got a Tough Stuff rocker guard gasket (body gasket) from 4wheelparts for $29.99. I thought why not? It's about 1/16" thick and rubbery. One side has a pattern and the other is adhesive. You attach it to the rocker guards, not tub. I scuffed up the powder coating with a Scotch Brite and cleaned with some acetone. Once attached you use a sharp razor and run it around the parameter of the rocker guard cutting off any extra.
I needed to loosen the front of the rear fender flares so I could slide the rocker guard into position. Once in position I tightened the rear fender flare. At this point I could let go and it stayed suspended, resting on the fender flares. I got a jack and jacked it up until the body moved up a little to make sure it was tight. I made sure it was fully against the side and bottom of the tub. I didn't have to worry about centering it, because it perfectly fit between the Xenon fender flares.
I then drilled the holes and installed the bolts, one at a time.
This was my first time doing this, but really simple to install. I like how they contour to the shape of the bottom of the tub.
Here it is all finished!
