This ^^^^ !!! Would make it look a lot better and even higher. With your offset I wouldn't to flares plus I like the clean look without them better. But if you are going to put flares on go with the 2500 flares for sure!
I vote for the OEM 2500 flares paint matched. Those look nice and clean and go with the our trucks really well in my opinion. Even the pocket style looks good if you have the right stance for it. But I would definately get them paint matched whichever you choose. Truck looks great man!
