Depends on the wheeling you do..... for some people like MFD, the stock ones would fold up.
Personally.... the Pure Jeep ones are junk... not anything wrong with the nerf bars themselves, but.... tub mounted items will bring on the suck very quickly. Tub mounted equals body damage. Kinda ironic when you think about it, no?
My suggestion would be to go frame mounted and not look back... sure you loose clearance and looks... but you get armor and I think that is what you are trying to buy.
Now... can the Con be done with your stock sliders? YES! Of course. I have run the Con when it was difficult one year.... every other time I have been, it's been doable in a stock Rubicon model.... the work that they are completing this year, we should see the trail doable in a 2wd vehicle before too long (saw the six foot tall piles of cement and hundreds of bars of rebar that was sitting at the top awaiting that week's work crew on Cadillac, saw the "keep out" signs at Soup Bowl (I now know!! lol), and it's my understanding that they have permanently blocked off Thousand Dollar Hill and are attempting to pave the Box). There are still plenty of lines left that you could work your sliders and watch them fail... so just watch your lines and you should be fine up there. Have fun, take pics, and report back!!
