That’s essentially the CBI slider. It’s about 0.5” narrower than the RCI kickout. I posted pictures above.Man, I'd like that RCI if it was the width of the kick out portion, but all the way to the front. A lot of these have some real goofy looking decks, if you want to use it as a step too. I'd like some that look like Tremor/Raptor running boards, the Gohino look good, but I have heard bad things about their quality. I know, not rock sliders.
