We have ACE rock sliders on our 2013 and they are awesome! Great steps and also protect your doors from dings. Nice and sturdy.
There were no dimensional changes between the 2013 and the 2014, so I don't think there will be any fitment issues. They are easy to put on, but you do need to modify two washers to fit. A cheap grinding wheel (~$20) from Harbor Freight does the job. I think you'd be much happier with the sturdiness of the ACE rails than the MOPAR side steps. ACE is steel, MOPAR steps are plastic.
Check out Northridge and Krawl OffRoad to see who has the best deal. They are both vendors here and have forum discounts/free shipping offers.
