Husky`s on all 4 corners. (OEM flaps ruin the paint, hold ALOT of snow/slush within them, due to a deep dish design at the bottom) I completely siliconed all the way around the mud flaps. No water or dirt can ever get between the mud flap and the body panels. Did not add the extra screw in each flap either, never had to on any of the other rams i`ve owned. Once siliconed, no damage to paint or wear factors, no flapping in the breeze going down the highway, not one issue using this install method. I even sealed up the whole wheel well(s) where the plastic inner fender protectors attach to the metal body panels, with black permatex silicone. All the mounting screws got siliconed to protect them from rusting as well. I`ve installed the factory stainless wheel to wheel step boards, almost touch the husky flaps on the front, i`m confident they`ll be just fine. Another thing i liked about the Husky`s, is the fact that they are wider, which is perfect for the sport trucks with the 20" tires. Having drove in crappy weather the last few days, the Husky`s have done a remarkable job keeping road debris off the side of the truck... something i cant say for the OEM flaps. Fit & finish of the Husky`s was very good, actually fit better than the OEM flaps on past rams i`ve had.
