The front rock guards are for the front 2015/16 Dodge Challenger and Hellcat. They come with 3M VHT mounting tape installed, and use existing mounting screws on the car. We also have the 2010 to 2014 Dodge Challenger front rock guard sets and come with same mounting tape. Both are made with mat finish plastic to match existing plastic on the car. The rears for the 2015/16 come with push pins to replace the OEM rivets removed as a option, or VHB tape option. The 2009/14 come with push pins to replace OEM rivets removed. THE OEM RIVETS ARE EASY TO REMOVE BY PUSHING CENTER PIN OUT AND RE USING OR INSTALL WITH PROVIDED PUSH PINS.
