I had Teraflex sliders on my last 4-door JK. They are considerably lighter than the stock Rubicon sliders, which is nice. I like the way they stick out and form a step, because it helps deflect rocks and other debree thrown by the front tires from hitting the body of the Jeep. But the step is just wide enough to slip off of when they are muddy, which is all the time if you 4-wheel in the mud. The step acts like a shelf to stack mud on , and you have to plow the mud off of the steps with the door when you open it. Then it is all but impossible to get into or out of the Jeep without rubbing your pant leg against the mud covered step. They become a real pain in the butt when the weather is anything but dry and sunny.
I saw a set of Teraflex sliders that did not hold up when they were used for sliders, and I am told it cost about $4000 to repair the damage to the Jeep's body. I did not see the damage to the Teraflex slider while it was occurring. I saw the Jeep parked at an offroad shop with the caved in Teraflex slider, so who knows what caused it. I was told he slid off a big rock and dropped onto his slider.
If what you really want is a step I would recommend Rockslide Engineering's slider steps.
